FVWM: FvwmSaveDesk Operation?

I like the FvwmSaveDesk module, but I was a bit confused why in the
man page seems to be more "updated" or something than the program. It
states that it creates a function called StartupFunction, when it
seems to create InitFunction (this seems more limited ? than
StartupFunction).

Also it would be nice I think to be able to specify a different file
than ~/.fvwmdesk. Also a different function name. Then one could
implement multiple dynamic save/restore desktop menus or something.

Here is a small patch, or start at least which changes the default
behavior to work like the man page says, and also adds two command
line options,

-file <outfile>

and

-func <funcname>

which alter the corresponding outputs accordingly (some unused vars
also removed). Sorry if this is already being worked on...
