Before we switched to one big test-tool binary, if you
forgot the name of a tool, you could use tab-completion in
the shell to get a hint. But these days, all you get is:
$ t/helper/test-tool approxidate
fatal: There is no test named 'approxidate'
and you're stuck reading the source code to find it. Let's
print a list of the available tools in this case.

Not really user-facing, but this bugged me enough earlier to write the
patch. ;)
Some of the individual tools have nice help, too (try
"t/helper/test-tool date", which shows the approxidate command I was
looking for), but some of them could probably stand to improve their
friendliness (try "t/helper/test-tool config"). I think it's fine for
people to improve them over time if and when they get annoyed.
