[PATCH 6/9] t1508 (at-combinations): test with symbolic refs

[Ramkumar Ramachandra <artagnon@gmail.com>]

Symbolic refs don't work with @{u}.  Document this failure.  Also
create a symbolic-ref @ (which is a valid ref name), and test
everything with it to make sure that there is no bug in the @-parser.
