mergetools: refine vimdiff warning message We explicitly redraw before echoing the message so that it simply displays at the bottom of the window. Also simplifies the message printing by using 'echomsg' (which uses 'echohl' internally) and adds the names of the software involved for improved Googleability.

mergetools: vimdiff issue a warning explaining how to abort Adds a message displayed at each vimdiff invocation: merge conflict detected, type ":cq" to abort Vimdiff is very confusing for non-vim user (not to speak about vim user confused anyway. However it is very likely that vimdiff is picked as the mergetool of choice when using the default config: - vim is available on all UNIX system. - Its one of the rare non graphical merge tools.

dispatch: also a separate warning message on aliases with --config As mentioned in bug 2043, --config is also not supported in an alias. So report this the same way as the other "early" options. Example with alias.broken = stat --config a.config=1 Before: $ hg broken abort: Option --config may not be abbreviated! After: $ hg broken error in definition for alias 'broken': --config may only be given on the command line

extensions: remove erroneous comment We actually -do- use the 'ui' argument to print a debug statement.

blackbox: do not translate the log messages User 'timeless' in irc mentioned that having the blackbox be translated would result in logs that: - may be mixed language, if multiple users use the same repo - are not google searchable (since searching for english gives more results) - might not be readable by an admin if the employee is using hg in his native language And therefore we should log everything in english.

scmutil: split platform-specific bits into their own modules This parallels what's done for the util module, which imports either mercurial.posix or mercurial.windows as 'platform' and then slurps the appropriate functions into its own namespace.
