Branch naming

[Christian Rose <menthos gnome org>]

Some maintainers seem to be already thinking on branching for 2.4. Let
me just remind people about the common style for naming of branches --
consistent branch naming helps everyone stay sane, not at least those
who often have to deal with branches for different modules.

This style is as follows:
* Use only lowercase characters in branch names. *Not* uppercase
(uppercase should be reserved for tag names)
* Use hyphens in branch names. *Not* underscores (underscores should be
reserved for tag names)
* Use the format "gnome-MAJOR-MINOR" for the branch name if your branch
is targeted for the GNOME MAJOR.MINOR release (things like the module
name or the word "branch" is superfluous information in branch names).

As an example, 

	gnome-2-4

would be an excellent choice for a branch name targetting the GNOME 2.4
release, and be in line with the branch names we've used in the past,
such as "gnome-1-4", "gnome-2-0", and "gnome-2-2".

*Bad* examples of branch naming would be things like:

	gfoo-GNOME24
	GNOME_2_4
	GNOME-2-4
	gnome_2_4
	gfoo-gnome-2-4
	gfoo-GNOME-2-4
	gnome-2-4-branch
	gnome24branch

and so on.


Thanks,
Christian
