[PATCH] git-prompt.sh: Document GIT_PS1_STATESEPARATOR

The environment variable GIT_PS1_STATESEPARATOR can be used to set the
separator between the branch name and the state symbols in the prompt.

At present the variable is not mentioned in the inline documentation which
makes it difficult for the casual user to identify.

Thanks, makes sense.

This is not a specification of a protocol or file or input/output  
format, where we formally use SP and LF.  Perhaps we could spell out  
SP as a space here, for the sake of the "casual user"?

Yes, I agree. Would it also be worth changing lines 25 and 29?
