It does.  For example, in my coreutils.git tree, running "git describe HEAD"
prints "v6.10-108-gd44893c", which indicates that is the 108th change
set since the v6.10 tag, and its SHA1 starts with "d44893c".

Doing the same for the previous SHA1:

    $ git describe b7a836c0a3524cda8ef79c30c3fe7ea759ae4656
    v6.10-107-gb7a836c
