[PATCH v2 00/19] Make git-am a builtin

[PATCH v2 00/19] Make git-am a builtin

[Paul Tan]

This is a re-roll of [v1]. Thanks Junio, Torsten, Jeff, Eric for the reviews
last round.

git-am is a commonly used command for applying a series of patches from a
mailbox to the current branch. Currently, it is implemented by the shell script
git-am.sh. However, compared to C, shell scripts have certain deficiencies:
they need to spawn a lot of processes, introduce a lot of dependencies and
cannot take advantage of git's internal caches.

This WIP patch series rewrites git-am.sh into optimized C builtin/am.c, and is
part of my GSoC project to rewrite git-pull and git-am into C builtins[1].
