Don't let ui.username override web.contact (issue900) 4603eef60237 introduced using ui.username before web.contact, but this was never documented and might cause commit accidents. - Drop web.author (deprecated since 2005) - Try ui.username or $EMAIL as a fallback to display something useful. - Update docs for the fallbacks.

bisect: improve tests - test skipping - test noupdate - test bad->good search - test inconsistent state

bisect: handle search for bad to good transitions Automatically detect whether we're looking for a bad to good transition rather than the usual good to bad transition by detecting when badrev is inside the good set and flipping good/bad.

bisect: make bisect a built-in command

bisect: faster merging

bisect: merge ancestor lists when pushing to children - eliminate some redundant tests and assignments - move ancestor list merging to child update

bisect: skip calculations on candidates with too many ancestors Once an ancestor list has grown past the perfect threshold, all descendants are less optimal. Use a poison dict to avoid pointless operations on their long ancestor lists, thus eliminating most of the work.

bisect: stop early if we find a perfect candidate

bisect: find best node in ancestor collection pass

bisect: calculate candidate set while finding children

bisect: use a dict for children We fill in the children only for ancestors of badrev

bisect: propagate ancestor lists directly to children - calculate the children of all candidates - for each candidate, combine ancestor lists - pass ancestor lists to children - store ancestor count This eliminates the O(n**2) memory usage, while maintaining about the same performance.

bisect: add noupdate option

Merge backout

Backed out changeset c2a21fe60994 Unfortunately, this breaks backward compatibility.

Show number of changesets written to bundle files by default (issue569) This was only shown with -v before.

"C" status code considered harmful, so changed to "=" (issue899) C means conflict in other SCMs, and = is more intuitive anyway.

Adjust changed test output after 0145f9afb0e7 (trailing whitespace)

Removed tabs and trailing whitespace in python files

util: filter all st_mode with 0777 in checkexec

merge with crew

Clarify some messages during commit: - use "branch 'foo'" to distinguish from "branch merge". - commit messags can be empty (to abort commits) - Added value for editor message: Tell about HG: lines like CVS does.
