As far as other languages go, I'm pretty sure python only requests
major+minor version. Perl's minimum versions are normally a full version
string, so truncating that probably wouldn't be a good choice. Another
option would be to truncate to just major+minor (in the inputs) only
when it comes time to print out the package.

Also, we don't want Guix to think 1.2.3 can only be upgraded to 1.2.3.4
and not to 1.2.4.
