But consider, for instance:
/bin/echo test -? somestring
vs: /bin/echo test -; somestring
if you don't quote the '-;', then the shell will use it
as a command-separator before the command ever sees it.
This seems to be true with sh, csh, and bash on my
freebsd-current system. This makes '-;' a very awkward
flag for a command to use. Seems like a nice extension
to getopt(3).
