Subject: Specify a different base for the imported patch
X-Git-Tag: v0.7~18
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/stgit/commitdiff_plain/35344f865c199e8457d951bc51b45d21f813cbc2

Specify a different base for the imported patch

This option will import a patch on a different base and perform a three-way
merge with the current HEAD.
