bundle2: localize handleoutput remote prompts Code archaeology suggests that there was no good reason for this not to be localized. 'remote: ' is already localized elsewhere.

i18n-pt_BR: synchronized with a12d13eac513

files: change documentation to match its behaviour (issue5276) Documentation gave the usage pattern as '[OPTION]... [PATTERN]...' when the command match given files as relpaths by default.

templater: add template path to __base__ search This does a fall-back check for style files or directories that are in Mercurial's template path for user convenience. We intentionally don't use this for the built-in coal style because we don't want the style to mysteriously break if the working directory just happens to have a file named "paper".

bundle2: fail faster when interrupted Before this patch, bundle2 application attempted to consume remaining bundle2 part data when the process is interrupted (SIGINT) or when sys.exit is called (translated into a SystemExit exception). This meant that if one of these occurred when applying a say 1 GB changegroup bundle2 part being downloaded over a network, it may take Mercurial *several minutes* to terminate after a SIGINT because the process is waiting on the network to stream megabytes of data. This is not a great user experience and a regression from bundle1. Furthermore, many process supervisors tend to only give processes a finite amount of time to exit after delivering SIGINT: if processes take too long to self-terminate, a SIGKILL is issued and Mercurial has no opportunity to clean up. This would mean orphaned locks and transactions. Not good. This patch changes the bundle2 application behavior to fail faster when an interrupt or system exit is requested. It does so by not catching BaseException (which includes KeyboardInterrupt and SystemExit) and by explicitly checking for these conditions in yet another handler which would also seek to the end of the current bundle2 part on failure. The end result of this patch is that SIGINT is now reacted to significantly faster: the active transaction is rolled back immediately without waiting for incoming bundle2 data to be consumed. This restores the pre-bundle2 behavior and makes Mercurial treat signals with the urgency they deserve.
