[18.57]  Here I am composing an email message, and say I want to tell
folks about the variable current-prefix-arg.
Say I do
(describe-variable 'current-prefix-arg)^U^X^E

I get
"Type C-x 4 b RET to restore old contents of help window."
stuck into my message, instead of the much more desirable
"current-prefix-arg's value is nil

Documentation:
The value of the prefix argument for this editing command.
It may be a number"...

This would require a simple adjustment of the return value of
describe-variable (while you're at it, check the behaviour of the
other describe-* commands).  [I guess it's no big deal that it still
pops the help window up on ^U^X^E.]
