.SH BUGS When a non-multivalued argument appears more than once on the command-line then only the last value supplied is used. A problem occurs however in the following scenario: suppose `\fB\-s\fP' is an option that takes an optional string argument (and suppose `\fB\-x\fP' is some boolean flag). Now, if the following command-line is issued: .XS command \-s string \-x \-s .XE then, even though it may appear as if the value used will properly correspond to the second instance of the `\fB\-s\fP' option, the value associated with the option will be ``\fIstring\fP'' (because the first instance overwrote the default and the second instance left the value untouched).
