X-BeenThere: freebsd-questions@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: User questions List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 09 Mar 2012 00:08:55 -0000 I've noticed for some time that claws-mail and less (which I think use libc's regex(3)) don't support word boundaries in searches. I might be delusional, but I think I've used \b in the past in both of those applications in FreeBSD. According to regex(3) it's an implementation POSIX.2, so the feature needn't be supported, but at the bottom of the page it says "word-boundary matching is a bit of a kludge", so presumably it has been. Does anyone know what's going on? I switched from i386 to amd64 last year so it might be something to do with that. I'm currently using 8.2p6.
