[PATCH] Add -k kill keyword expansion option to git-cvsimport - revised

Early versions of git-cvsimport defaulted to using preexisting keyword
expansion settings. This change preserves compatibility with existing cvs
imports and allows new repository migrations to kill keyword expansion.

After exploration of the different -k modes in the cvs protocol, we use -kk
which kills keyword expansion wherever possible. Against the protocol
spec, -ko and -kb will sometimes expand keywords.

Should improve our chances of detecting merges and reduce imported
repository size.

DESCRIPTION
@ -38,6 +38,11 @@ OPTIONS
ensures the working directory and cache remain untouched and will
not create them if they do not exist.
-k::
Kill keywords: will extract files with -kk from the CVS archive
to avoid noisy changesets. Highly recommended, but off by default
to preserve compatibility with early imported trees.
-o <branch-for-HEAD>::
The 'HEAD' branch from CVS is imported to the 'origin' branch within
the git repository, as 'HEAD' already has a special meaning for git.
