While translating GCC (to Swedish), I've occasionally come across obviously truncated strings. Often, it has been caused by multiple lines used for the description in .opt files. I've tried to file reports about them.
One such report I made in late 2007. In 2011 I got the suggestion to send in patches instead. See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34352 for details. That I'll do, I thought. And promptly forgot about, apparently. But better late than never! I've finally made myself a little script to discover those cases, and merged the descriptions into one line. I attach the suggested diff here.
