[PATCH v4 0/2] Libify rerere: clear and gc

[Ramkumar Ramachandra <artagnon@gmail.com>]

Hi,

This is an alternate version of the v3 patch: Instead of exposing
unlink_rr_item, I have chosen to libify "rerere gc" in order to libify
"rerere clear", and it may be argued that this is a pleasant
side-effect.  I've also included another patch to replace the
"die_errno" call with a new "error_errno" call, and I hope this will
be used in other places as well.  Note one more subtle change: I've
chosen to pass "flags" as an argument to both functions for the sake
of consistency; if and when rerere grows more command-line options,
"flags" can be replaced by a struct containing those parsed options.

Cons: This patch is much larger than v3.

Thanks to: Junio and Jonathan.
