regexp---remove comments---simplification

[Gary Turner <kk5st@sbcglobal.net>]

Not an earth-shattering problem.  I try to remove all those comments
from various config files before emailing them to wherever.  I currently
chain some greps

grep -v '^\ *#' some.conf | grep -v '^\ $' > condensed.file

How would you combine these regexp's to remove a commented line (even if
indented) and a blank line?  My various permutations and combinations
have resulted in errors.
