bug#49910: [website] script generating POT files broken with guile@3.0.7

[pelzflorian (Florian Pelz)]

Hello Guix!

In the guix-artwork.git repo, the pot file generation
(scripts/sexp-xgettext.scm as described in the file i18n-howto) in the
website is broken since guile@3.0.7.  Old guile@3.0.2 works.

The issue is at the end of the procedure in the call to (read) within
token->string-symbol-or-keyw, specifically

guile -c '(with-input-from-string ",@" (lambda () (read)))'

I will investigate, but I don’t fully understand.

Regards,
Florian
