[PATCH 0/3] fix memory leak in git-am

[Jeff King <peff@peff.net>]

This was noticed by Coverity. The leak isn't new, but I think was
"re-found" by Coverity because some nearby code did an unrelated
s/sha1/oid/ change, throwing off its heuristics.

I also checked whether this was in Dscho's big pack of Coverity fixups
from earlier today, and it's not.

The first one is the actual fix. The second one is pure cleanup, but I
think worth doing. The final one is arguably just churn, and maybe
people even like the end result less. I'm OK to drop it.

  [1/3]: am: fix commit buffer leak in get_commit_info()
  [2/3]: am: simplify allocations in get_commit_info()
  [3/3]: am: shorten ident_split variable name in get_commit_info()
