5748693b91 add_commit_patch_id(): avoid allocating memory unnecessarily
It would appear that we allocate (and forget to release) memory if the
patch ID is not even defined.

b6b066adf9 winansi: avoid buffer overrun
When we could not convert the UTF-8 sequence into Unicode for writing to
the Console, we should not try to write an insanely-long sequence of
invalid wide characters (mistaking the negative return value for an
unsigned length).

3057da5ad5 winansi: avoid use of uninitialized value
To initialize the foreground color attributes of "plain text", our ANSI
emulation tries to infer them from the currently attached console while
running the is_console() function. This function first tries to detect any
console attached to stdout, then it is called with stderr.

If neither stdout nor stderr has any console attached, it does not
actually matter what we use for "plain text" attributes, as we never need
to output any text to any console in that case.

However, after working on stdout and stderr, is_console() is called with
stdin, and it still tries to initialize the "plain text" attributes if
they had not been initialized earlier. In this case, we cannot detect any
attributes, and we used an uninitialized value for them.

Naturally, Coverity complained about this use case because it could not
reason about the code deeply enough to figure out that we do not even use
those attributes in that case.

Let's just initialize the value to 0 in that case, both to avoid future
Coverity reports, and to help catch future regressions in case anybody
changes the order of the is_console() calls (which would make the text
black on black).

1a845a2c88 mingw: avoid memory leak when splitting PATH
In the (admittedly, concocted) case that PATH consists only of path

54fd3243da rebase -i: reread the todo list if exec touched it
In the scripted version of the interactive rebase, there was no internal
representation of the todo list; it was re-read before every command.
That allowed the hack that an `exec` command could append (or even
completely rewrite) the todo list.

This hack was broken by the partial conversion of the interactive rebase
to C, and this patch reinstates it.

We also add a small test to verify that this fix does not regress in the
future.

1f9e18b772 prio_queue_reverse: don't swap elements with themselves
Our array-reverse algorithm does the usual "walk from both
ends, swapping elements". We can quit when the two indices
are equal, since:

  1. Swapping an element with itself is a noop.

  2. If i and j are equal, then in the next iteration i is
     guaranteed to be bigge than j, and we will exit the
     loop.

So exiting the loop on equality is slightly more efficient.
And more importantly, the new SWAP() macro does not expect
to handle noop swaps; it will call memcpy() with the same src
and dst pointers in this case. It's unclear whether that
causes a problem on any platforms by violating the
"overlapping memory" constraint of memcpy, but it does cause
valgrind to complain.

627fde1025 submodule_init: die cleanly on submodules without url defined
When we init a submodule, we try to die when it has no URL
defined:

  url = xstrdup(sub->url);
  if (!url)
	  die(...);

But that's clearly nonsense. xstrdup() will never return
NULL, and if sub->url is NULL, we'll segfault.

These two bits of code need to be flipped, so we check
sub->url before looking at it.
