RPM has used hyphens since its inception.  Except for a small number of
releases, RPM has disallowed hyphens in version and release
specifications.  At least since version 2.0.x, RPM has allowed hyphens
in package names.

Programs that deal with package specifications (name-version-release)
directly pretty much do what the following awk scriptlet describes:

  awk -F '-' '{
    if (NF < 3) {
      printf("Bad package specification: \"%s\"\n", $0)
    } else {
      printf("name=\"%s", $1)
      for (i = 2; i < (NF - 1); i++) {
        printf("-%s", $i)
      printf(" version=\"%s\"", $(NF - 1))
      printf(" release=\"%s\"\n", $NF)

: p.s. Is the best place to post a question like this?  The response has
:      not been, um, overwhelming...

Yes, it is.  I suspect folks have simply been busy with other things.
