Before, the help text said that Mercurial would assume 'yes' for all
prompts, but this is confusing since many prompts don't have any 'yes'
choice. It now more accurately describes what will happen.
The verb to allow requires a direct object.
Lintian, a Debian tool to find common mistakes, reported it. I'm not a

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.
