And people might also want to use tag names like qtop and qparent. Mq is
already messing with namespaces.

My proposal is a tradeoff between:

- adding an option to -lots- of commands (and the related maintenance
hassle of making sure we add -Q to all new commands where it might make
sense) and effectively burning -Q for any other use for any other
command or extension

- adding a single magical name in the [paths] namespace only when mq is

While namespace collisions are best avoided, there's actually more
namespace pollution in the first approach than in the second.
