Subject: git-shortlog: make common repository prefix configurable with .mailmap
X-Git-Tag: v1.5.0-rc0~212^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=7595e2ee6ef9b35ebc8dc45543723e1d89765ce3;p=git.git

git-shortlog: make common repository prefix configurable with .mailmap

The code had "/pub/scm/linux/kernel/git/" hardcoded which was
too specific to the kernel project.

With this, a line in the .mailmap file:

	# repo-abbrev: /pub/scm/linux/kernel/git/

can be used to cause the substring to be abbreviated to /.../
on the title line of the commit message.
