hook: fix full path imports on Windows (issue1779) Bottom portion fixes full path imports on source installs on Windows. The top portion further fixes full path imports on binary installs. Initial patch by Roman V. Kiseliov

patch: marked string for translation

diffstat: scale adds/removes proportionally to graph width The previous method of scaling had a tendency to include graph lines that went past the output width when the file with the most changes had a very large number of changes.

test-clone-failure: reenable perm to allow deletion

patch: create file even if source is not /dev/null as long as the first hunk is -0,0 and the source and destination have the same name. Matt found a patch like this, and /usr/bin/patch accepts it.

dispatch: also pass level argument to __import__ for ignored modules I wanted to check if mercurial.demandimport could speed up the loading of PyObjC, and ran into this: the level argument for __import__, available in Python 2.5 and later, is silently dropped when doing an 'import *'. I have no idea what these arguments mean, but this minor change made it work. (Oh, and because of that 'from ... import *', PyObjC still took about 2s...)

lsprof: make profile not die when imported modules changes (issue1774)
