Subject: Ask git about unmerged files
X-Git-Tag: v0.15-rc1~335
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/stgit/commitdiff_plain/d4f2b3e9bc83fd6e3063c856e3f1f203dcc5b304

Ask git about unmerged files

Don't look in the "conflicts" file for that, since it isn't updated. Also
added a test that the check_conflicts() function works.
