test-lib: Print missing prerequisites in test output

avar · gitster · commit 71ce42c0a6b3 · 2010-08-18T12:42:04.000-07:00
Change the test output to print needed prerequisites as part of the
TAP. This makes it easy to see at a glance why a test was
skipped. Before:

    ok 7 # skip &lt;message&gt;
    ok 9 # skip &lt;message&gt;

After:

    ok 7 # skip &lt;message&gt; (prereqs: DONTHAVEIT)
    ok 9 # skip &lt;message&gt; (prereqs: HAVEIT,DONTHAVEIT)

This'll also be useful for smoke testing output, where the developer
reading the output may not be familiar with the system where tests are
being skipped.
