[PATCH] services: 'console-keymap-service' takes multiple files.

[Alex Kost]

"loadkeys" can take multiple files as arguments, and this may be useful
in practice (as discussed with suitsmeveryfine on #guix¹).  So
'console-keymap-service' should be modified accordingly.

Subject: [PATCH] services: 'console-keymap-service' takes multiple files.

* gnu/services/base.scm (console-keymap-service-type): Type procedure
takes a list of files instead of a single file.
(console-keymap-service): Take 'files' as rest arguments.
* doc/guix.texi (Base Services): Improve documentation of
'console-keymap-service'.

+keymap, which can be done like this:
+
+@example
+(console-keymap-service "dvorak")
+@end example
+
+But also you can specify a full file name (or file names) of your
+keymap(s).  See @code{man loadkeys} for details.
