> 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'.
