commands: improve help for -y/--noninteractive Before, the help text said that Mercurial would assume 'yes' for all prompts, but this is confusing since many prompts don't have any 'yes' choice. It now more accurately describes what will happen.

bookmarks: simplify warning code

bookmarks: drop superfluous strip

bookmarks: add a warning for non empty malformed line

bookmarks: more robust parsing of bookmarks file

merge with stable

revsets: catch type error on tip^p1(tip) (issue2884)

revsets: do the right thing with x^:y (issue2884) Given an operator ^ that's either postfix or infix and an operator : that's either prefix or infix, the parser can't figure out the right thing to do. So we rewrite the expression to be sensible in the optimizer.

win32mbcs: wrap two more functions to be wrapped. util.checkwinfilename() and util.checkosfilename() are wrapped. The former, used by scmutil, is not friendly for Shift_JIS bytes. The latter is an dynamic alias of checkwinfilename() used by other modules.

commands, merge: call setconfig on the right ui In practice this doesn't change anything since ui == repo.ui here, but setting repo.ui explicitly here is clearer since hg.merge will use repo.ui later on.
