[plt-scheme] drscheme feature idea: automatically add missing exports for scheme modules

Here's a DrScheme feature that I could really use:  a command that would 
add to the "provide" form of the module in the editor any names defined 
in the module but not exported currently, *except* those with names 
beginning with the character "%".

A somewhat less-ideal feature would include "%" symbols as well, and I 
could just manually delete those.

"%" is a convention that I stole from (I believe) Olin Shivers for 
marking names internal to the library.  A feature like I described could 
support that convention in a generalized way by permitting the user to 
use regexps to specify which names to exclude.
