Unix and VMS agree on "*" as a "match any number of any chars"

wildcards, but differ ("?"  vs.  "%") for their "match any single
char" wildcard.  This patch changes "?"  chars to "%" before doing a
VMS glob...at no loss of functionality, since "?"  isn't a valid
filename char on VMS.  From Charles Lane.
