gEDA-user: Verbosity in gEDA/pcb documentation

It's not cut and paste, it's a programmatic macro inserted by the
document extractor.  The ":" one is like this:

/* %start-doc actions wq

This command has been added for the convenience of @code{vi} users and
has the same functionality as @code{s} combined with @code{q}.

@colonaction

%end-doc */

Where @colonaction is defined earlier in that file (src/command.c).
