bug#71952: documentation inaccuracy?

[Simon Tournier]

Hi,

>> $ guix home switch-generation -- -1
>> guix home: error: -1: extraneous command

Indeed, the command-line parser seems incorrect and inconsistent with
the documentation.

The culprit seems the procedure ’parse-args’ from ’guix-home’ command
inside the module (guix scripts home).

Hum, I guess something as the attached patch should fix the issue.

diff --git a/guix/scripts/home.scm b/guix/scripts/home.scm

WDYT?
