Introduce GIT_PS1_DESCRIBE option you can set to "contains", "branch", or
"describe" to tweak the way how a detached HEAD is described.
The default behaviour is to describe only exact match with some tag
(otherwise use the first 7 hexdigits) as before.

* I do not think the new modes based on name-rev (aka "--contains") are
much useful if you do your own development while on a detached HEAD,
but they probably are useful for tourists who sightsee.
