Guile reader package names are problematic

[Mark H Weaver]

Hi Ludovic,

In commit d9d466ddff2091f4b1f94599335b5947a17def2c, you added the
following packages:

  guile-reader-for-guile-1.8.8
  guile-reader-for-guile-2.0.7

The "1.8.8" and "2.0.7" are actually part of the package names (both of
these packages are at version 0.6).

Unfortunately, this means that these packages cannot be referenced using
the guix command-line tools, because 'package-name->name+version'
assumes that "1.8.8" or "2.0.7" is the version number, and that the
package name is "guile-reader-for-guile".  It then fails to find any
package of that name.

How do you suppose this should be fixed?
