Added tag 1.8.1 for changeset aa1f3be38ab1

i18n-pt_BR: synchronized with 66d65bccbf06

tests: use $TESTTMP more and use (glob) less This locks down the test output a little more.

hgweb_mod: respond right away if the client specified 100-continue support Clients that send 100-continue should make sure they really support continue intelligently. In a later patch we'll introduce a capability so new clients don't pay a performance penalty talking to old servers.

hgweb: add support for 100-continue as recommended by PEP 333.

subrepo: show the source that git pulls

commands.update() now works properly with a revision of 0 Without this change commands.update() treats an integer 0 as if no revision was passed and updates to the branch head. This fix allows an integer 0 to be detected as a revision number so the working directory is correctly changed to revision 0 rather than the branch head.

merge with stable

mergetools: add alternate registry keys for 32bit apps on 64bit O/S Not all applications needed the workarounds, so I did not add alternate keys for every Windows merge application.

filemerge: introduce a 'regkeyalt' merge tool variable This allows us to provide alternate search keys for 64bit operating systems that may have 32bit merge tools installed. Presumably it may find other uses.
