Reported by Mohammed AMAR-BENSABER &lt;renken@shione.net&gt;.

Previously 'read-with-comments' would enter an infinite loop.

* guix/read-print.scm (read-with-comments)[missing-closing-paren-error]:
New procedure.
Call it when 'loop' as called from 'liip' returns EOF.
* tests/read-print.scm ("read-with-comments: missing closing paren"):
New test.
