grep: refactor loop that yields matched text with label
As preparation for formatter support, this and the next patch split
linestate.__iter__() into two functions, line scanner and displayer.
New code uses regexp.search(str, pos) in place of regexp.search(substr),
which appears to fix a bug of highlighting.

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

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.
