Computed strings like impede correct internationalization.  The whole
sentences must be kept intact, to make sure people can translate them
correctly.  So that means repeating things a bit, but that’s
unavoidable.

Ideally, I would just like to see:

 The following packages will be upgraded:
    file-5.17	out	/gnu/store/...
    guile-2.0.9	out	/gnu/store/...

and not see them listed under “will be installed.”

I would just keep the current messages for this patch series, and come
up with an improved message format in a separate patch.

WDYT?

Thanks,
