bug#51493: [PATCH 0/5] Improvements to the pypi, cran, and "print" importers

[Ludovic Courtès]

Ludovic Courtès <ludo@gnu.org> skribis:

>   import: pypi: Allow imports of a specific version.
>   import: cran: Allow imports of a specific version.
>   import: print: Properly render packages with origins as inputs.
>   import: print: Correctly handle URI lists.
>   import: print: Handle patches that are origins.

Pushed as b2ed40c29f578d46d42cb1c5e99bd797cea3aba0, topped with this
extra commit in the same vein:

  3756ce3267 import: print: Replace packages and origins in 'arguments'.

I’ll have to take care of the merge conflicts with ‘core-updates-frozen’
in print.scm…
