--- Comment #5 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- If multi-line descriptions are to be disallowed (and it does appear they are outside the .opt format as presently documented in options.texi), then opt-read.awk should generate an error on encountering such a description, so such descriptions produce an immediate build failure rather than just quietly causing translation problems.
