Thanks for the report.  However, this is not a bug, but a misunderstanding
on your part of what POSIX requires.

'dirname -- -file' is the correct way to invoke dirname on something
starting with -.  POSIX does not require the support of any options, but
it ALSO does not forbid any options as extensions.  POSIX is quite clear
that except for a few special cases (such as test and echo), users of
utilities specified by POSIX must properly separate filenames from options
using -- if the filename could be interpreted as an option, because
implementations are allowed to add options as extensions.

Don't work too hard, make some time for fun as well!
