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.

The previous error message was the same in many situations (unknown
revision or path not in the working tree). We try to help the user as
much as possible to understand the error, especially with the
sha1:filename notation. In this case, we say whether the sha1 or the
filename is problematic, and diagnose the confusion between
relative-to-root and relative-to-$PWD confusion precisely.
The 7 new error messages are tested.
