Description:

This worked prior to the latest build:

noremap <silent> <F3> :set hlsearch!<CR>

Now it capitalizes 3 characters and leaves matches highlighted.

Additional info:

$ pacman -Ss vim |grep installed
extra/gvim 7.3.712-1 [installed]
extra/vim-runtime 7.3.712-1 [installed]

Plugins are Pathogen and...
$ ls .vim/bundle/

Steps to reproduce:

1. Add the above mapping to .vimrc or enter it in the Vim command bar
2. Enable search highlighting:
:set hlsearch
3. Add some text you want to match:
isome foo some other foo[Esc]
4. Search for some text: /foo
5. [F3] should clear the highlighting, but will capitalize the current character and the next two
