I'm new to vim (for the seventh time) so this may not be something that makes sense for vim style but: The command history in the command window has up-arrow mapped to history and this has been very helpful in learning, except that it does not seem to store commands that fail to execute in the history. Obviously, this is a bad configuration choice for someone trying to learn from mistakes. Is there a way to force it to remember the failed commands, in the sense that they can be recalled with the up-arrow?
FYI, I am using MacVim with Janus extensions.
