Remove bogus raise from localrepo.lookup()

Fix hg qdiff <file>

Ignore EPIPE in pipefilter This hides the following traceback (there's a race condition involved, so you may have to try a few times to hit it): $ hg sign --key key-that-does-not-exist Signing 2062:4bad92f4ea65 gpg: skipped "key-that-does-not-exist": secret key not available gpg: signing failed: secret key not available Exception in thread Thread-1: Traceback (most recent call last): File "threading.py", line 442, in __bootstrap self.run() File "threading.py", line 422, in run self.__target(*self.__args, **self.__kwargs) File "mercurial/util.py", line 24, in writer pin.close() IOError: [Errno 32] Broken pipe abort: Error while signing

Don't send "Content-Type: none" mimetypes.guess_type will return (None, None) when it can't detect the filetype.

Fix filerevision-raw.tmpl Two bugs: - conteXt-type instead of conteNt-type - trailing newline The easiest way to fix the second one (and keep it fixed) is to put everything inline in map-raw.

convert-repo: fix reversed time zone offset

catch SIGBREAK on windows.

update windows readme to document msys/mingw rxvt problems.

fix util.canonpath on windows. old test for absolute path was not portable. use os.path api instead.

make appendfile simpler so it does not break with revlogng on windows. it used to cache open files. this made revlogng break because it wants to rename files when splitting .i into .i/.d, but cannot rename or unlink open files on windows. new code is bit slower, but safe on linux and windows. proper fix for too many open/close of changelog/manifest belongs in different place. can get 10% speed improvement back.
