Personally, I don't like filenames with special meanings (as not every
OS has /dev/fd we would have to treat them specially), or filenames that
become non-extensible mini-languages by themselves. Many other
command-line options use the key=value syntax, and some already have an
"fd" option, so this just follows the convention.

Also, this is more extensible to allow more options to be added to
-readconfig if needed (for example: debugging options, or the
help=defconfig option I added on the RFC series I sent after this one).
