Hey, there could even be another option for the commit command, call it
the -b option, which creates a branch with the provided tag name. This was
also an option of ther CM systems I've used.

This fits in nicely with the senario that Gerhard Fiedler suggested, a
senario that I'm drawn to more and more.

All I'm saying is that if you want to use tags or branches or bug id's to
create a subset of your files you should be able to create (or add to) that
subset at the most logical point i.e. when you commit.  If it is a seperate
command to do this you are more likely to forget something or do something
else wrong.
