I encountered this, too, and it severely impacts automated testing of Vim
plugins. (I was hit by this recently, sorry that I didn't yet report it; I'm
glad that the example mapping from Douglas shows the problem so succinctly.)
I'm using my runVimTests framework
(http://www.vim.org/scripts/script.php?script_id=2565) to test-drive my plugins,
and naturally invoke mappings with :normal, and then typically check the text
modifications via getline(). Using feedkeys() is no alternative in this case,
because these keys are only processed after the driving Vim test function
returns, so the getline() within that function that aims to verify the mapping
finds that the mapping hasn't yet run, and that there are no modifications! I
had to use very ugly workarounds (manually setting g:count, and using that in my
plugin) to get mappings with <count> tested at all!
In general, I try to avoid feedkeys() in mappings, because I found that it also
doesn't play well with recorded macros (those keys are processed out-of-order at
the end of the macro).
I really hope that the :normal <count> issue can be fixed, as this is a
showstopper for automated tests.
