Formatting comment lines (C code)

[luca.spinacci@seleniacomms.com]

I would like to format my comment lines
replacing all spaces and tabs between
'//' and the comment text with only one space.
Ex.
//____Text.... => //_Text

where '_' is a space.

I use replace-regexp "[^ a-zA-Z0-9/\.]" " "
on a selection of my code but it
doesn't work very well because replaces
characters in the comment text
- for instance replaces )(!-, etc. -.

Any suggestion?

Thank you very much.
Luca
