[issue3125] Branch name with colon ":" allowed

[Fabian Kreutz]

New submission from Fabian Kreutz <fabian.kreutz at qvantel.com>:

The branch subcommand allows creating branches with a colon (":") inside, 
although that is invalid.
Such a branch cannot be addressed e.g. in "update", as first matches against 
revision intervals  and fails with an unhelpful error message.

It says clearly in "hg help revision" that a colon is not allowed in branch 
and tag names, so the "hg branch" subcommand should abort instead of creating 
that branch.

Proposed patch is attached.
