patch: explicitely close input patch files when leaving If applydiff() raises an exception, the opened patch file is kept alive in the exception context. If it is a temporary file (for instance supplied by import command with stdin input), Windows cannot clean it up.

hgweb: improve IIS PATH_INFO fix ee8af8a4d905 (issue1580) Copy PHP IIS detection.

Minor svn conversion tests cleanup

subrepo: force en_US.UTF-8 locale when calling svn Parser only knows about en_US output. Forcing the encoding to UTF-8 might not be the best thing to do since the caller may receive some of the subversion output, but at least it should prevent conversion errors from svn client.

test-subrepo-svn: normalize OS specific path separator

subrepo: normalize svn output line-endings

mq: qdiff with the same diff options than qrefresh (issue1350) Specifically, if current patch is a git patch and mq.git=keep, diff in git mode.

mq: upgrade to git patch when necessary (issue767)

patch: support diff data loss detection and upgrade In worst case, generating diff in upgrade mode can be two times more expensive than generating it in git mode directly: we may have to regenerate the whole diff again whenever a git feature is detected. Also, the first diff attempt is completely buffered instead of being streamed. That said, even without having profiled it yet, I am convinced we can fast-path the upgrade mode if necessary were it to be used in regular diff commands, and not only in mq where avoiding data loss is worth the price.
