Hi,
I remember Nick Gravgaard already needed such option and I wrote a simple vim
script doing that, with no patch. It is not ideal of course (no events used,
for example - one must press a hot key with this alpha version of the script)
but it shows the problem probably has a solution even using vim script language
only. What do you think?
