[help-gengetopt] cmdline_file_save accepts file handler instead

[Papp Gyozo (VBuster)]

Hi there,

another simple question or "begging" (depends on your attitude) has come to my 
mind.

It would be great if the generated config file saver function (or an 
alternative one) could accept FILE* pointer instead of a filename, because this 
way it would be easy to implement `--show-config' feature which dumps the 
current settings e.g to stdout (like. gcc -dump* options do)

Background. One of our product has a fairly complex initialization procedure 
(where to lookup for config file(s) -- system default, customized user and so 
on). So it sometimes takes considerably long time to figure out the exact 
configuration with what the program had launched.

Saving to file is OK but in some cases it is preferrable to dump it simply to 
the stdout (ie. in script and such)
