Positive, I've got a mapping which do :cd %:h then :grep, this mapping works since Vim 6.3, 6.4 and 7.0, this is the mapping I used "Everyday" and I cannot use Vim without it, then suddenly it breaks after I installed Vim 7.1. ---- Now I changed :cd %:h to :cd %:p:h and everything works. Anyway, I think there should be an option to disable E500, or "catch and throw". This is the Unix trend: if the caller feel necessary, a program should fail silently in order not to break a script.
