[bug#50314] [PATCH 0/2] Add hint typo for importers and system actions

[zimoun <zimon.toutoune@gmail.com>]

Hi,

Instead of,

        $ guix import pypy foo
        guix import: error: pypy: invalid importer

it becomes

        $ ./pre-inst-env guix import pypy foo
        guix import: error: pypy: invalid importer
        hint: Did you mean `pypi'?

And thanks to Sarah, the --options are also hinted (when typo).

Note that it is not possible to guess which importer is between 'cpan' and
'cran' for the typo 'can'.  The first from the list 'importers' is returned,
i.e., 'cpan'.

Last, instead of

        $ guix system sarch cuirass
        guix system: error: sarch: unknown action

it becomes

        $ ./pre-inst-env guix system sarch cuirass
        guix system: error: sarch: unknown action
        hint: Did you mean `search'?


All the best,
simon
