highlight nice foo

Similarly to #107, which highlights the command after sudo, one could highlight the command after nice.

The problem is options parsing: see 19981ef and 3b3a58b for an analogous example.

There are many other commands that accept an execve-able argument list; some common ones are env, xargs, and find ... -exec. Perhaps it would be better, instead of hardcoding N separate option parsers, to hook into completion system (issue #10) and ask compsys to identify command words for us?

compsys already solved the "parse find's command line" problem, and I don't want to have to repeat that exercise. ☺

[ That said... if it's possible to support nice, or env, or any other single utility, in a simple manner without adding lots of twisty codepaths, that might be worthwhile as an interim measure until #10 is fixed ]

Let's add strace to the list of affected commands, too.
