inotify: check all components of filenames against hgignore (issue884) With inotify enabled, files that should be ignored could be detected as untracked by mercurial. This behavior was wrong because inotify's filestatus implementation only matched filenames against ignore patterns, instead of checking if other elements of their paths matched them. This patch fixes the behavior by checking the file paths against the ignore patterns. A new test has also been added to the main inotify test to prevent any regressions.

hg.clone: fix branch value when passing a repo object (issue2267) Since 3d6915f5a2bb the branch argument for addbranchrevs should be a tuple: (hashbranch, branches) The right empty value therefore is (None, []) instead of None.

test-bheads: use a case-insensitive set of filenames (issue2274) This prevents false negatives on case-insensitive systems.

mail: ensure that Python2.4 to 2.7 use the same header format Wrapping format for long headers changed in Python2.7 (see Python issue1974). Adopt the Python2.7 behaviour and backport it for 2.4-2.6

filelog: cmp: don't read data if hashes are identical (issue2273) filelog.renamed() is an expensive call as it reads the filelog if p1 == nullid. It's more efficient to first compute the hash, and to bail early if the computed hash is the same as the stored nodeid. 'samehashes' variable is not strictly necessary, but helps for comprehension.

filelog: test behaviour for data starting with "\1\n" Because "\1\n" is a separator for metadata, data starting with "\1\n" is handled specifically. It was not tested. size() call return incorrect data if original data had been "\1\n-escaped". There's no obvious way to fix it for now, just flag the error in the code and add an "expected failure" kind of test.

cmp: document the fact that we return True if content is different This is similar to the __builtin__.cmp behaviour, but still not straightforward, as the dailylife meaning of a comparison usually is "find out if they are different".
