replay/stupid: raise the correct errno in IOError to fix hg >= e553a425751d Basically, all the IOErrors we ever raise inside a file commit function that is sent to commitctx should be ENOENT. This suggests a change should be made in commitctx to not overload IOError.

import imp, os, sys

sys.path.insert(0, os.path.dirname(os.path.dirname(__file__)))
