extdiff: merge node and working dir snapshot modes

convert/p4: win32 fixes * cmd.exe does not know single quotes * win32 does not like trailing whitespace very much. Trade test coverage for maintenance time and drop the trailing whitespaces tests.

test-issue1438: make executable

context: fix workingctx.__contains__

run-tests: detect when hghave fails to check for a feature and fail test hghave exitcode != 0 might mean that hghave failed to check for feature avaibility. Detect those cases, and fail the test, instead of skipping it.

hghave: checking that all targets are Exception-free

Add Python 2.6 support to win32 installer With Python 2.6, win32 installer should try to package MSVC9.0 dlls instead of MSVC7.1 dlls

Bundle python dll in win32 installer if present in case hg.exe is generated with the py2exe '-b 2' option instead of '-b 1', python2?.dll is not included in library.zip file and must also be packaged. The file will be integrated in the installer only if it is present in the dist directory. Generating hg.exe with the '-b 2' option is mandatory to avoid a crash when pyreadline is installed.

Win32 installer: add hgrc.5.html and hgignore.5.html links to Start Menu folder

test-convert-svn-sink: rewrite output for svn compatibility Addition by Patrick Mezard <pmezard@gmail.com>: * drop 'kind=' lines from svn 1.6 output

convert/cvs: delay CVS log parsing after initialization (issue1581/2) Source and destination constructors should be fast so configurations issues are hit quickly, including authentication and filemap/authormap/splicemap issues. Delaying might be a problem if the remove side disconnects idle connections while the log is being read. It did not happen when converting openafs repository, where log retrieval took at least 10mn.

convert: better mapfile parsing errors (issue1581/1)

convert/bzr: fix file rename replaced by a dir case (issue1583) We were not checking entry types, and getting file content was working with directories instead of raising IOError.

purge: fix b777dd8f7836 (remove read-only files) - use try/except to avoid unnecessary work - edit only mode bits

Fix manifest default rev doc when no rev is checked out (issue1603)

commands: more informative description of "!" files in status This makes the description more similar to the one used by Subversion. Suggestion by Dennis Brakhane.

commands: automatically word-wrap cmdline options Some of the descriptions of command line options were getting quite long, and when translated they are likely to grow even longer. This word-wraps them at 70 characters, just like the help texts. We could have opted to wrap them at the terminal width instead, but I think it looks better to have them be consistent with the help texts.
