Some kind of :-)

1) From a usability point of view, this should be part of "guix import"
since this is what the user does and where she is looking for help.

2) "guix build --source" returns a derivation, whereas "guix import"
ought to return the original, unchanged source. (One could argue that on
"import", the derivation is the unchanged source depending on nothing)

3) Of course one could use the output of "guix import", pass it to "guix
build --source" and get the original source. But
a) this would download the source twice
b) would intermix phases: the package definition is in early draft, but
"build" should return the source. This does not match.

4) In any case, "guix import" should display the name of the downloaded
archive.
