fancyopts: lots of cleanups

commit: avoid losing edits during commit If a file is edited between the time we record file states in the repo and update the dirstate, that change can be lost to hg status. Because we invoke the editor between these two points, that window can be arbitrarily large. This greatly shrinks the window by recording the commit change immediately. If our checkin fails, we simply invalidate the dirstate.

rm: complain more about removing added files

merge: make return codes more sensible Commands that call merge were exiting with a return code equal to the number of unresolved files. We now return 1 if there are unresolved files.

doc: correct preoutgoing description

dispatch: report OOM rather than traceback

Merge with crew-stable

convert: move commands definition to ease demandload job (issue 860)

win32: remove text man pages from Windows package The HTML versions are still packaged, and do not suffer from eoln problems. This solves issue531 (addition through subtraction)

Merge with mpm

win32: include zsh_completion in Windows package

win32: include contrib/vim in Windows package

win32: use relative path to install source Remove hard-coded path to the source repo to be packaged.

win32: move default install path inside program files All of the 'space in path' problems have been resolved, so we can install Mercurial the Windows standard location. The {pf} InnoSetup variable is locale aware.

win32: it is no longer necessary to bundle patch.exe Mercurial can use it's built-in mpatch library

win32: do not install bash hgmerge on Windows
