[PATCH] test: optionally print subtest number

[David Bremner]

From: David Bremner <brem...@debian.org>

The idea is that $test_count could be used in tests to label
intermediate files. The output enabled by this patch (and --debug)
helps figure out which OUTPUT.nn file belongs to which test in case
several subtests write to OUTPUT.$test_count
---

Is there something that depends on the test format? I find it pretty
handy to have the subtest numbers, but I don't want to break some
other tools. I followed the existing style of conditionally defining
functions, but maybe someone with more bash-fu can improve that.
