man page mis-documents `poptCallbackType`

[FGasper]

In popt.h:

typedef void (*poptCallbackType) (poptContext con, 
		enum poptCallbackReason reason,
		const struct poptOption * opt,
		const char * arg,
		const void * data);

popt.3 has:

.BI "void poptCallbackType(poptContext con, 
.BI "                      const struct poptOption * opt, 
.BI "                      const char * arg, void * data);

The man page needs the reason argument added.

Thank you!

Also the const qualifier from the header should probably be in the man page.
