merge: stop emptying out 'cd' and 'dc' actions (1) These aren't currently read from anywhere, so emptying this out is pointless. (2) These *will* be read from later in upcoming patches, and not emptying them out will be important then.

rebase: add returning value from pullrebase function So far pullrebase function has always returned None value, no matter what orig function returned. This behaviour made impossible for pull to change returned value from mercurial process (it has always ended with 0 value by default). This patch makes pullrebase returning with returned value from orig.

resolve: restore .orig only after merge is fully complete (issue4952) Previously, we'd restore the .orig file after the premerge is complete but before the merge was complete. This would lead to the .orig file potentially containing merge conflict markers in it, as a leftover from the last merge attempt.

monoblue: add a space to separate navigation links in file log footer Before: '(0)-60tip', after: '(0) -60 tip'.

merge: move messages about possible conflicts a litte earlier I actually wanted to reduce the amount of code around the call to applyupdates(), so I tried moving these warnings a little earlier, and I think it makes the output make a little more sense (see changes to test cases).

import-checker: include lineno in warning message This makes it easy to look for imports in function scope.

import-checker: extract function to generate a formatted warning This is the stub to embed lineno. See the next patch for details.

import-checker: make it executable for convenience
