Hello,

(Apologies if this is the wrong list to send to.)

Attached are three tiny patches that add to glob(3) a flag which, if
set, allows glob metacharacters to match an inital dot in a filename.
I've copied the name of the option, GLOB_PERIOD, from GNU glob.

Please let me know if there's further work I should do to get this
change incorporated.

Thanks,
Richard Kreuter
