ui: add configlist doctest to document a bit more of the whitespace behavior I'm surprised this wasn't explicitly tested, so I added a test.

merge stable into default

Added signature for changeset 0ccb43d4cf01

Added tag 4.4 for changeset 0ccb43d4cf01

test-dispatch: stabilize the test When cwd is removed and `hg` is executed, some shells may run `getcwd` before forking and executing, some may not do it, some may print a different error message. The test should be shell-independent so let's just avoid checking the error message. Differential Revision: https://phab.mercurial-scm.org/D1282
