Amazingly, timegm(gmtime(0)) is only 0 before 2020 because perl's
timegm deviates from GNU timegm(3) in how it handles years.
man Time::Local says
Whenever possible, use an absolute four digit year instead.
with a detailed explanation about ambiguity of 2-digit years above that.
Even though this ambiguity is error-prone with >50% of users getting it
wrong, it has been like this for 20+ years, so we just use 4-digit years
everywhere to be on the safe side.
We add some extra logic to cvsimport because it allows 2-digit year
input and interpreting an 18 as 1918 can be avoided easily and safely.

Commit 5b4efea666 (cvsimport: shell-quote variable used in
backticks, 2017-09-11) tried to shell-quote a variable, but
forgot to use the "/g" modifier to apply the quoting to the
whole variable. This means we'd miss any embedded
single-quotes after the first one.

We run `git rev-parse` though the shell, and quote its
argument only with single-quotes. This prevents most
metacharacters from being a problem, but misses the obvious
case when $name itself has single-quotes in it. We can fix
this by applying the usual shell-quoting formula.

We had this in "git merge" manual for eternity:
'git merge' <msg> HEAD <commit>...
[This] syntax (<msg> `HEAD` <commit>...) is supported for
historical reasons. Do not use it from the command line or in
new scripts. It is the same as `git merge -m <msg> <commit>...`.
With the update to "git merge" to make it understand what is
recorded in FETCH_HEAD directly, including Octopus merge cases, we
now can rewrite the use of this syntax in "git pull" with a simple
"git merge FETCH_HEAD".
Also there are quite a few fallouts in the test scripts, and it
turns out that "git cvsimport" also uses this old syntax to record
a merge.
Judging from this result, I would not be surprised if dropping the
support of the old syntax broke scripts people have written and been
relying on for the past ten years. But at least we can start the
deprecation process by throwing a warning message when the syntax is
used.
With luck, we might be able to drop the support in a few years.

On many platforms, the first invocation of localtime_r will
check $TZ in the environment, but subsequent invocations
will use a cached value. That means that setting $ENV{TZ} in
the middle of the program may or may not have an effect on
later calls to localtime. Perl 5.10.0 and later handles
this automatically for us, but we try to remain portable
back to 5.8. Work around it by calling tzset ourselves.

Certain characters such as "?" can be present in a CVS tag name, but
git does not allow these characters in tags. If git-cvsimport
encounters a CVS tag that git cannot handle, cvsimport will error and
refuse to continue the import beyond that point.
When importing CVS tags, strip all the inappropriate strings from the
tag names as we translate them to git tag names.
Provide more debugging information to the user if we've altered the
tag and the "git tag" command still fails. Also, warn the user if we
end up skipping an (unusable) tag altogether.

The current code leads to
fatal: bad config value for 'cvsimport.r' in .git/config
for a standard use case with cvsimport.r set.
cvsimport sets internal variables by checking the config for each
possible command line option. The problem is that config items are case
insensitive, so config.r and config.R are the same. The ugly error is
due to that fact that cvsimport expects a bool for -R (and thus
config.R) but a remote name for -r (and thus config.r).
Fix this by making cvsimport expect long names for uppercase options.
config options for cvsimport have been undocumented so far, though
present in the code and advertised in several tutorials. So one may read
"enhance" for "fix". Similarly, the names for the options are
"documented" in the code, waitiing for their lowercase equivalents to be
transformed into long config options, as well.

Change the Perl scripts to turn on lexical warnings instead of setting
the global $^W variable via the -w switch.
The -w sets warnings for all code that interpreter runs, while "use
warnings" is lexically scoped. The former is probably not what the

As an auxiliary benefit it's now possible to build Git with:

Formalize our dependency on perl 5.8, bumped from 5.6.[12]. We already
used the three-arg form of open() which was introduced in 5.6.1, but
t/t9700/test.pl explicitly depended on 5.6.2.
However git-add--interactive.pl has been failing on the 5.6 line since
it was introduced in v1.5.0-rc0~12^2~2 back in 2006 due to this open
syntax:
sub run_cmd_pipe {
my $fh = undef;
open($fh, '-|', @_) or die;
return <$fh>;
}
Which when executed dies on "Can't use an undefined value as
filehandle reference". Several of our tests also fail on 5.6 (even
more when compiled with NO_PERL_MAKEMAKER=1):
t2016-checkout-patch.sh
t3904-stash-patch.sh
t3701-add-interactive.sh
t7105-reset-patch.sh
t7501-commit.sh
t9700-perl-git.sh
Our code is bitrotting on 5.6 with no-one interested in fixing it, and
pinning us to such an ancient release of Perl is keeping us from using
useful features introduced in the 5.8 release.
The 5.6 series is now over 10 years old, and the 5.6.2 maintenance
release almost 7. 5.8 on the other hand is more than 8 years old.
All the modern Unix-like operating systems have now upgraded to it or
a later version, and 5.8 packages are available for old IRIX, AIX
Solaris and Tru64 systems.

There were two problems:
1. We only look at the config variable if there is no module
given on the command line. We checked this by comparing
@ARGV == 0. However, at the time of the comparison, we
have not yet parsed the dashed options, meaning that
"git cvsimport" would read the variable but "git
cvsimport -a" would not. This is fixed by simply moving
the check after the call to getopt.
2. If the config variable did not exist, we were adding an
empty string to @ARGV. The rest of the script, rather
than barfing for insufficient input, would then try to
import the module '', leading to rather confusing error
messages. Based on patch from Emanuele Giaquinta.
