[bug#67009] [PATCH] build: minetest-build-system: Improve white space handling in mod name field.

[Tristan Cottam]

I'm currently developing a Minetest service, with its configuration
including a field specifying the list of mod packages to install and
enable.

However, certain mods' configuration, beind developed on Windows, have a
trailing carriage return before each newline, which is included in the
Guix store mod directory base name. Such mods can't be programmatically
loaded by a Minetest world, since trailing whitespace is ignored by
Minetest's world configuration parser, leading to the wrong mod path
being used.

This patch fixes certain Minetest mods being stored with a terminating
carriage return in their directory base name.

* guix/build/minetest-build-system.scm (name-regexp): Improve white
space handling.
