[Vimoutliner] color schemes messed up

[Claus Atzenbeck]

Hi all,

I started using vimoutliner and I like it. However, apparently it messes
up the color schemes of other (non-otl) documents. I am using vim 7 (not
gvim) in the Terminal on Mac OS X.

For example, when I open ~/.vimrc, vim uses a specific color scheme.
That's fine.  However, when I open the same file *after* opening an .otl
file, .vimrc looks completely different. For example, keywords like
"map" suddenly appear in bold face vimoutliner has been loaded.

I changed the ~/.vim/colors/vo_dark.vim file, because it produced many
bold fonts (which are nowhere defined). Even LineNr changed from normal
font to bold after vimoutliner was loaded.

How can I force vimoutliner only to touch .otl relevant colors, but not
others? Especially the fact that suddenly many bold face fonts appear
makes me wonder, because I don't see any ":hi xxx cterm=bold" defined in
.vim/*.

Thanks for any hint.
Claus
