Vim is highly configurable. See ":help nrformats" for supported formats.
Not clearly documented in the version I have, but implied, is setting
it to a blank string to only recognize ordinary decimal numbers.

Thanks for the tip.  I'll look into that.

Yes, nf looks good.  I set it to "alpha", which makes it do the right thing
with letters, while ignoring the stupid hex/octal/bin stuff.

And one more thing...

It seems nf is buffer-local, so setting it while in one buffer does not
change it globally.  Setting it in .vimrc does set it globally (which makes
sense, since no other buffers exist at that point - and they all inherit
the value).

I get why this is the way it works, but am curious if there is a way to set
it globally (without exiting and re-starting VIM, of course).  I have lots
of windows and buffers open and don't want to re-start.

I read "help :set" and it covers a lot, but didn't see anything
specifically on this topic.
