dispatch: ignore further SIGPIPE while handling KeyboardInterrupt...

dispatch: ignore further SIGPIPE while handling KeyboardInterrupt I got the following error by running "hg log" and quitting the pager immediately. Any output here may trigger another SIGPIPE, so only thing we can do is to swallow the exception and exit with an error status. Traceback (most recent call last): File "./hg", line 45, in <module> mercurial.dispatch.run() File "mercurial/dispatch.py", line 83, in run status = (dispatch(req) or 0) & 255 File "mercurial/dispatch.py", line 167, in dispatch req.ui.warn(_("interrupted!\n")) File "mercurial/ui.py", line 1224, in warn self.write_err(*msg, **opts) File "mercurial/ui.py", line 790, in write_err self._write_err(*msgs, **opts) File "mercurial/ui.py", line 798, in _write_err self.ferr.write(a) File "mercurial/ui.py", line 129, in _catchterm raise error.SignalInterrupt mercurial.error.SignalInterrupt Perhaps this wasn't visible before because the original stderr handle was restored very late.
