ui: edit(): rebase, graft: set HGREVISION environment variable for an editor rebase and graft commands set 'rebase_source' or 'source' extras for the revision. Allow an editor to access the extras using HGREVISION environment variable. This may be useful when an editor is actually a script which modifies a commit message. The name 'HGREVISION' has been selected as transplant already sets this variable for its filters (--filter).

cmdutil: make commitforceeditor() to pass revision extras to ui.edit()

ui: allow edit() to work with revision extras Make edit() to accept optional 'extra' dictionary. Revision extras will be used in upcoming patches to set some environment variables.

tests: glob match has a glob character for not getting a warning on windows When / matches on / on windows, and there is no other glob character, this results in a warning. Avoid this by using an other glob character.

run-tests: fixed warn detection on failures with too many output The state "warned" was reported too often. The problem fixed here is that warnonly was only reset when a line did not match. When there was a line too much, warnonly remained set. Fix this by setting more states to warnonly. More negative testing (testing on result "Failed") has been done this time.

run-tests: fixed warn detection on detecting warn only for lines The state "warned" was reported too often. The main problem was that "False == 0" is true in python. Therefore use an empty string instead of 0 for reporting warn only for a line. The other problem is fixed in the next patch.

obsolete: extract encoding of marker for pushkey from the list key function We now have a function taking a list and marker and returning an encoded version. This will allow obsolescence marker exchange experimentation to easily pushkey-encode markers to be pushed after selection.

solaris: diff -u emits "No differences encountered" Solaris diff -u isn't silent when two files are identical, and tests that don't account for that will fail. Fix those tests, and introduce a check that prevents reintroduction.

rebase: do not raise an UnboundLocalError when called wrong (issue4106) When the base is not found, we should not raise a traceback about a not defined variable. This hides the real problem: the function rebasenode was (probably) called wrong. An AssertionError is raised to highlight that the caller of the function did something wrong. An alternative approach is to only assign None to the variable "base" and let the merge mechanism raise an abort message. This was the behaviour for this case before ad9db007656f. But the only known case for this problem is when an extension calls this function wrong. An AssertionError makes this clearer than an abort message. When a different case is detected, the behaviour can be improved then.

exchange: fix docs for pulloperation 'remote' is actually the remote, not the repo one is pulling into. This confused me quite a bit.
