[issue2040] mandatory "--" in qguard command help usage syntax

[Ross]

New submission from Ross <Ross.Johnson at homemail.com.au>:

This is a somewhat pedantic change request hence I've selected the "wish"
priority for it.

The usage syntax shown by "hg help qguard" specifies the "--" flag as
mandatory when it is conditional. Of course it won't break anything to
include it but it just isn't always needed.

It shows:
hg qguard [-l] [-n] -- [PATCH] [+GUARD]... [-GUARD]...

The following is a truer description and doesn't make it too complicated
(noting that patch names can't start with "+" or "-").

hg qguard [-l] [-n] [PATCH] [-- [+GUARD]... [-GUARD]...]

Obviously there are many variants and more complete ones also.
