/* Because we permit long options to start with a single dash, and
we have a --library option, and the -l option is conventionally
used with an immediately following argument, we can have bad
results of somebody tries to use -l with a library whose name
happens to start with "ibrary", as in -li. We avoid problems by
simply turning -l into --library. This means that users will
have to use two dashes in order to use --library, which is OK
since that's how it is documented.
FIXME: It's possible that this problem can arise for other short
options as well, although the user does always have the recourse
of adding a space between the option and the argument. */
