I don't think that would actually help anything in this case. "This
program's embedded regexps are misinterpreted by a newer libc.so" is
not noticeably different from "This program's embedded regexps are
misinterpreted if the program has been recompiled with newer glibc".
Especially when it has to do with a corner case like whether . matches
\n.  Release notes are probably the best we can do here.
