The help text displayed is the same as for the super command (show).

Looks like it's actually another bug.

"darcs help show patch-index" is the command you want to use

"darcs help show patchindex" or "darcs help show blabla" should not
work. But they currently show the same output as "darcs help show".
They should probably fail instead.

No idea what made me think it would be 'show patchIndex'. Perhaps it was
the name of the option in the code.

Resolved, at least in the head:

ben@home[4]:~>darcs help show bla | head -5
Invalid subcommand!

Usage: darcs show SUBCOMMAND [OPTION]...
