Many tests didn't change back from subdirectories at the end of the tests ...
and they don't have to. The missing 'cd ..' could always be added when another
test case is added to the test file.
This change do that tests (99.5%) consistently end up in $TESTDIR where they
started, thus making it simpler to extend them or move them around.
This speeds up the in-memory version of debugbuilddag that I'm
working on considerably for the case where we want to build just
a 00changelog.i (for discovery tests, for instance).
There are a couple of test changes because node ids in tests
have changed.
The changes to the patch names in test-mq-qdelete.t were required
because they could collide with nodeid abbreviations and newly
actually do (patch "c" collides with id "cafe..." for patch "b").
When mq status entry referencing a patches that is not in series `hg qfinish
-a` used to issue a traceback. This states is inconsistent but might happen
regularly when people misuse hg up -mq.
This changeset prevent hg from crashing. The faulty entry is finished anyway and
a warning is issued.
When using a versioned patch repository, you would get a spurious
warning when deleting and adding the same patch.
Before:
$ hg qdelete --keep 3.diff
$ hg qimport --existing 3.diff
adding 3.diff to series file
3.diff already tracked!
After:
$ hg qdelete --keep 3.diff
$ hg qimport --existing 3.diff
adding 3.diff to series file
