You're going to hate this, but now that I see the example in the manual,
I'm wondering why "prefix:" and "command:" are on separate lines?
Why not just imitate the syntax that comes out of the help command -

	set symbol-reloading -- <help string>
	show symbol-reloading -- <help string>

Another advantage is that users can then cut-n-paste from the apropos
output more easily.

Just needs approval from one of us, not both!  I must confess to being
a bit mystified by the test though - why use "handle" as the match
string, and do I understand right, you're requiring that it be the
first output from apropos?
