I thought the `left-most' part was a given and we were discussing which of the alternatives would be subsequently picked; sorry if I was misleading. In this case POSIX specifies that the alternative which gives the longest overall match is picked, whereas backtracking implementations (like that in Vim) are usually designed to pick the first alternative that gives an overall match, even if a different choice would give a longer overall match. I know you know this already, I'm just trying to be clear! Now, I'm still not sure I've managed to do that, so please rephrase my explanation for me if you think it is necessary :-) --Antony --~--~---------~--~----~------------~-------~--~----~ You received this message from the "vim_dev" maillist.
