This commit introduces tests that verify that rev-parse
parses master@{n} correctly for various values of n less
than, equal to and greater than the number of revisions
in the reference log.
In particular, these tests check that rev-parse exits with a
non-zero status code and prints a message of the
following form to stderr.
fatal: Log for [^ ]* only has [0-9][0-9]* entries.
