Fixes <https://issues.guix.gnu.org/61201>.
Previously, common practice was to splice arbitrary strings (user names,
file names, etc.) into Texinfo snippets passed to 'display-hint'. This
is unsafe in the general case because at signs and braces need to be
escaped to produced valid Texinfo. This commit addresses that.
* guix/ui.scm (texinfo-quote): New procedure.
(display-hint): When ARGUMENTS is non-empty, pass it to 'texinfo-quote'
and call 'format'.
(report-unbound-variable-error, check-module-matches-file)
(display-collision-resolution-hint, run-guix-command): Remove explicit
'format' call; pass 'format' arguments as extra arguments to 'display-hint'.
