It stands for "use long options", because it used to be a wrapper for the
now-defunct _long_options completer (which was completely subsumed by
_arguments some while back).

However, note that all it does is call _arguments, which is what 98% of
the completers for other commands also do. So most commands for which
there is a special completion already have the ability to complete based
on --help output: It's triggered by completing after `--'. Try, for
% tar --<TAB>
and watch the fun.
Which reminds me, Sven: There's still the bug where setting the `menu'
style to `select=N' for some number N is not working at all. Menu
selection never starts for me.

This is very interesting.
The earliest mention of _use_lo in the zsh-workers archive is PWS saying
"What happened to _use_lo? I don't remember removing it." just before he
made the 3.1.6-test-1 release. That's the first time it shows up in my
home CVS repository, too. The ChangeLog-Release file doesn't mention it
at all until Sven started patching it (and the entire contents except for
the comment at the top have long been Sven's doing, even if he didn't
create the file originally).
Of course, the ChangeLog also doesn't make any mention of when _arguments
acquired the internals of _long_options.
