Hmm, how about taking Dscho's "default GIT_UNZIP to /usr/local/bin/unzip
on FreeBSD" thing, together with something like this, then?
I suspect that 4 checks that look at $extracted/* after running
unzip -a should probably be inside a single test that runs unzip -a,
simply because they do not make any sense if the extraction failed,
but I did not fix that with this.

test: check "unzip" and "unzip -a"
Different platforms have implementations "unzip" that behave
differently. Most of the tests we use GIT_UNZIP we only care about
the command to be able to extract from *.zip archive, but one test
in t5003 wants it to also be able to grok the "-a" option.
Prepare a sample zip file that has a single text file in it, and try
extracting its contents to see GIT_UNZIP is usable. when setting
UNZIP prerequisite. Similarly, set UNZIP_AUTOTEXT prerequisite by
running GIT_UNZIP with the "-a" option.
