+1; a BIG +1.

You can use `Package Requires ((foo "0"))' as a workaround, but it's
silly that you have to do that.  If a library is not versioned, or if
for some reason any version of it will do for the package that requires
it, it should be possible to use just `Package Requires ((foo))'.

Furthermore, if no library is required, it should be possible to omit
a `Package-Requires' altogether - that should be equivalent to
`Package-Requires ()'.
