I've noticed a handful of false positives in guix lint checking
descriptions and synopsis, and tracked several down to the use of
@code{} and similar.

The attached patch partly addresses this, though could definitely be
written better (e.g. handling more cases, also stripping out the
relevent "}", etc.)

This fixes about 11 out of 544 overall guix lint issues with
descriptions and synopsis. Had expected it to fix more issues, but I
think stripping the "@code{" reveals issues in other checks that were
previously hidden.... maybe.

I will reiterate that this leaves a lot of room for improvement. :)
