Test repository filtering avoidance
===================================
This test file is a bit special as he does not check feature, but performance related internal code path.
Right now, filtering a repository comes with a cost that might be significant.
Until this get better, ther are various operation that try hard not to trigger
a filtering computation. This test file make sure we don't reintroduce code that trigger the filtering for these operation:
Setup
-----
$ hg init test-repo
$ cd test-repo
$ echo "some line" > z
$ echo a > a
$ hg commit -Am a
adding a
adding z
$ echo "in a" >> z
$ echo b > b
$ hg commit -Am b
adding b
$ echo "file" >> z
$ echo c > c
$ hg commit -Am c
adding c
$ hg rm a
$ echo c1 > c
$ hg add c
c already tracked!
$ echo d > d
$ hg add d
$ rm b
$ cat << EOF >> $HGRCPATH
> [devel]
> debug.repo-filters = yes
> [ui]
> debug = yes
> EOF
