I had disregarded that because there is neither beep nor message, nothing happens at all when the cursor is in column 1. I also thought that my .vimrc timeout setting of
set notimeout ttimeout ttimeoutlen=200
accounted for the different behaviors, but issuing
:set timeout timeoutlen=200 ttimeout ttimeoutlen=200
in the buffer before using the mapping makes no difference.
