explicitly turn the flag off, as well as turning it on, (usually to
override default options). This is usually done by using a
.RB ` + '
-instead of a
+instead of a
.RB ` \- '
to introduce the option. (Some programs use upper-case option letters
to indicate this instead.)
.I longind
variable, passed to
.B mdwopt
-(unless
+(unless
.I longind
is null): a value of \-1 indicates that no long option was found. The
behaviour is then dependent on the values in the table entry.
