patchbomb: save introductory message in .hg/last-email.txt

opener: forbid paths ending with directory separator (issue2507) If Linux is asked to open a filename with a trailing directory separator, e.g. "foo/", the open fails with EISDIR. On AIX, the open succeeds, opening file "foo". This causes test-mq-qnew to fail on AIX. Fix by adding 'ends with directory separator' to the conditions checked by the path auditor. Change test to expect auditor fail message.

record: clean up command table The --force option to qnew has become a no-op, so qrecord doesn't need to use it. This allows record's command table to be simplified; in the process of doing so, this patch also cleans up the cmdtable visually.

record: clean up comments and docstrings Rewrap comments and docstrings to a width of 72 chars and copy-edit.

test-doctest: test url.py again, removed by 7cc4263e07a9

extensions: warn about invalid extensions when listing disabled commands Invalid extensions in hgext/ could in some cases cause a crash when searching for unknown commands in disabled extensions. With this change we issue a warning if extracting commands from the extensions fails. Traceback is available on request. Reported on https://bugzilla.redhat.com/show_bug.cgi?id=663183 with forest.py.

convert: subversion should use util.quotecommand to wrap args to popen2 All other callers of util.popen2 and util.popen3 do this, as well as direct callers of subprocess.Popen.
