diff: disable diff.noprefix option for diffstat (
issue5759)
We could use patch.diffhunks() instead of patch.diff() to get filenames
without parsing patch content, but that isn't always possible because we
sometimes feed raw patch data to patch.diffstat().
Init repo1:
$ hg init repo1
$ cd repo1
$ echo "some text" > a
$ hg add
adding a
$ hg ci -m first
$ cat .hg/store/fncache | sort
data/a.i
Testing a.i/b:
$ mkdir a.i
$ echo "some other text" > a.i/b
$ hg add
adding a.i/b (glob)
$ hg ci -m second
$ cat .hg/store/fncache | sort
data/a.i
data/a.i.hg/b.i
Testing a.i.hg/c:
$ mkdir a.i.hg
$ echo "yet another text" > a.i.hg/c
$ hg add
adding a.i.hg/c (glob)
$ hg ci -m third
$ cat .hg/store/fncache | sort
data/a.i
