[PATCH] t1401: test symbolic-ref exit codes on a non-symbolic ref

[Nikolaus Schuetz via GitGitGadget]

From: Nikolaus Schuetz <nikolauspschuetz@gmail.com>

git-symbolic-ref(1) documents that reading a name that is not a
symbolic ref exits with a non-zero status, and that --quiet does so
silently rather than printing a diagnostic.  This was not tested.

Check that querying a non-symbolic ref exits 128 with the usual
"is not a symbolic ref" message, and that --quiet instead exits 1
with no output.

    t1401: test symbolic-ref exit codes on a non-symbolic ref
    
    git-symbolic-ref(1) documents that reading a name that is not a symbolic
    ref exits with a non-zero status, and that --quiet does so silently
    rather than printing a diagnostic. This exit-code contract was untested.
    
    This adds two tests: querying a non-symbolic ref exits 128 with the
    usual "is not a symbolic ref" message, and --quiet instead exits 1 with
    no output.
    
    Test-only; documents existing behaviour, in the spirit of 919eb8ace
    (t1402: check for refs ending with a dot).
