That's a regex problem. Our regex(3) doesn't like [^][:]. That's meant to be a single character class: match any char but ']', '[', or ':'. The issue is that the sequence [: is special and starts a standard character class name, e.g. [:alpha:]. I don't know if that particular RE or our regex engine should be considered at fault, but reordering the characters from [^][:] to [^]:[] fixes this particular instance. -- Christian "naddy" Weisgerber na...@mips.inka.de
