Subject: merge-base --fork-point: extract libified function
X-Git-Tag: v2.20.0-rc0~91^2~3
X-Git-Url: https://git.lorimer.id.au/gitweb.git/diff_plain/103148aad80ee7ab65b902d77d964260cfd3f6ea?hp=103148aad80ee7ab65b902d77d964260cfd3f6ea

merge-base --fork-point: extract libified function

We need this functionality in the builtin rebase.

Note: to make this function truly reusable, we have to switch the call
get_merges_many_dirty() to get_merges_many() because we want the commit
flags to be reset (otherwise, subsequent get_merge_bases() calls would
obtain incorrect results). This did not matter when the function was
called in `git rev-parse --fork-point` because in that command, the
process definitely did not traverse any commits before exiting.
