I suggest renaming `apropos-variable' to `apropos-option' and to
use `apropos-variable' for 

  (let ((apropos-do-all t)) (call-interactively 'apropos-variable))

or something equivalent.

Users assume functions to do what their name suggests, the hint in
the interactive prompt that `apropos-variable' does not really list
all variables but just user options is not enough IMHO.
