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.
util: concentrate quoting knowledge to windows.py quotecommand()
This fixes all callers of util.quotecommand() and place special knowledge
of the bugfix in 2.7.1 in a single platform specific place.
tests: clean up test-rollback.t
The last comment is on the last file line and is useless, seems
like it was introduced in
