* gnu/packages/linux.scm (config->string): add a clause handling strings
Allows for the declarative configuration of kconfig options which accept
strings, such as CONFIG_MODULE_SIG_KEY.
I've enclosed the given string in quotes, but don't do any kind of
escaping. See the kernel mailing list for the current state of escaped
strings upstream:
https://patchwork.kernel.org/project/linux-kbuild/patch/1431003982-992-1-git-send-email-sr@denx.de/
Apologies to those with double-quotes or backslashes in their
CONFIG_SYSTEM_*_KEYS.

Applied.
If needed, a cheap and often “good enough” way to escape strings is
‘object->string’:
(display (object->string "foo\"bar\"baz"))
=> "foo\"bar\"baz"
Would that help here?
Thanks,
Ludo’.

Without digging into kconfig to see exactly what's going on, I'm
afraid that anyone using risky characters (especially ['`\n#$]) in one
of these fields is on their own.
Single-quoted strings appear to be interpreted as empty regardless of
their content, so that's not an option. Within double-quoted strings,
it doesn't appear to allow you to escape single-quotes, quisi-quotes,
or #comments. While double-quotes and backslashes only need a single
escape (which does line up with object->string), (semi-)colons need
two, and a pipe only works with four ("\\\\\\\\|" in a guile source
file). "$" breaks in ways that I frankly don't understand, and which
no amount of escaping resolves. I'm perfectly content to assume that
people will only use [a-zA-Z0-9/+-_. ], and [[\]!@%^&*()={},<>?] also
happen to work just fine.
Thanks for taking the time to review my patch, and for all the work
you've done, within Guix and the broader Guile ecosystem alike.
