I have set up MacVim as my man pager with the following in my .profile

export MANPAGER='col -bx | /Applications/MacVim.app/Contents/MacOS/Vim -c ":set 
ft=man nonu nolist nomodifiable" -R -'

Now executing man will invoke MacVim to display the man page. However, after 
upgrade to MacVim 7.4 Snapshot 70, syntax highlighting of man pages no longer 
works. Basically, man headings NAME, SYNOPSIS, OPTIONS etc are not syntax 
highlighted, but command options are (of course you must have syntax 
highlighting turned on in your .vimrc).

I have attached a sample man page rendered with groff the same way man filters 
it before it passes it to vim for viewing. If you open the attached man.man, 
MacVim 7.4 will correctly detect the file type, but syntax highlighting doesn't 
quite work. If you open the same file in MacVim 7.3 it is syntax highlighted 
properly. 

Also, starting with MacVim 7.4 some man pages like system linker 'man ld' have 
weird "^[[2;2R" string at the beginning of the first line, that disappears 
after page refresh with CTRL+l.

Here is output of :scriptnames (it looks like correct syntax/man.vim is used 
Line 32):

 35: ~/.vim/nerdtree_plugin/fs_menu.vim

By the way diffing syntax/man.vim between version 7.4 and 7.3 shows no 
differences.

I just got response from Bram Moolenaar on this issue and it looks like syntax 
highlighting problem is base vim problem (he said he would fix it soon) but I'm 
still baffled by the weird string in the first line :D.
