--- Comment #1 from Jilles Tjoelker <jilles@FreeBSD.org> ---
The patched version ignores getopt(1)'s output except for the number of
iterations of a loop. This drops necessary adjustments made by getopt(1) su=
ch
as changing -ab to -a -b.

As noted in the BUGS section of getopt(1), fixing arguments with whitespace=
 and
shell metacharacters is hard. With the current API, it is not possible.

A reasonable solution for shell scripts is to use the getopts builtin inste=
ad
of getopt(1). This fixes the problems with special characters and poor error
messages and simplifies the code in the script. The man page could recommend
this more.

If you insist on using something called "getopt" or want to use long option=
s,
an alternative is to use a non-standard mode of the misc/getopt port.
