run-tests: add possibility for test-runners to report a "warned" test result
A test result is recognized as "warned" when the test runner returns the exit
code False. (False is similar to 0, which is reporting a command has run
sucessfully.)
The only difference in display is that the failure message while running writes
"Warning:" instead of "ERROR:". The diff output is the same as when the test
fails. Runing "run-tests.py -i" asks to accept the changed result also for
tests reported as "warned".
When running tests, a "warned" test would look like this:
..
--- xxxx\tests\test-something.t
+++ xxxx\tests\test-something.t.err

$ echo anything
$ hg commit -S -m whatever

- committing subrepository s/sbs
+ committing subrepository s/sbs (glob)
warning: something happened
committing subrepository t
$ echo something
Warning: xxxx\tests\test-sOMETHING.t output changed
~.s...s...s..
Reporting a test result as "warned" will be used in following patches.
run-tests: separate exit code when no failed tests but warned ones
This can be used by buildbot to set the result "warnings" instead of "failed".
run-tests: introduce 'warned' as test result
While running, a test resulting in 'warned' is shown as '~'.
Test results with state warned are listed between the skipped and the failed
tests. Example:
Skipped test-revert-flags.t: missing feature: executable bit
Skipped test-inotify-lookup.t: missing feature: inotify extension support
Warned test-something.t: output changed
Failed test-largefiles.t: output changed
Failed test-subrepo.t: output changed
# Ran 11 tests, 2 skipped, 1 warned, 2 failed.
The test result "warned" will be used in later patches.
run-tests: remove unnecessary variable initialisation
ret is always set before it is used, so remove ret = 0
histedit: clarify description of fold command
N and (N-1) didn't add any information to description of fold.
More useful is refering to the commit list as it is displayed in editor.
discovery: make "note: unsynced remote changes!" less serious than a warning
This situation is not necessarily a problem and do not deserve a warning. It is
just some information that can guide the user in understanding what is going
on.
Making it 'debug' would usually not give the hint when it is relevant so we
make it a 'status' message.
discovery: improve "note: unsynced remote changes!" warning
This message frequently caused confusion. "unsynced" is not a well established
user-facing concept in Mercurial and the message was not very specific or
helpful.
Instead, show a message like:
remote has heads on branch 'default' that are not known locally:
6c0482d977a3
This message will also (when relevant) be shown before aborting on "push
creates new remote head".
A similar (but actually very different) message was addressed in
