<br />Thanks for your help. I'm running sr-2.2.8 on a 64bit kernel in Mac OSX 10.6.8 which is Snow Leopard.<br />Apple just released 10.7.1 Lion, but I have not checked this issue there.<br /><br />Mac native sed is turkey fiddles (try to say that 10 times fast).<br />So list_elvi() takes a pecking and misbehaves.<br />If I replace sed with gsed in that function, it works. And by "works" I mean it works in the way <br />you could replace Charlie Sheen with an ear of corn, and it would work better as an actor and be <br />infintely more elegant.<br /><br />Sadly though, gsed is not native. So I figure I'd mention it. If this is fixed in a HEAD, my bad.<br />nibbles<br />
