>Description:
Note: this PR is not DragonFly specific.

The vim editor in pkgsrc (editors/vim) is build by default without cscope 
support. cscope is a handy tool for every developer, so the support should be 
build-in by default. I know there is a knob to add --enable-cscope, but it's 
turned off.

It is perfectly possible to add cscope support to vim without depending on 
cscope itself (either for building or running). If you don't have cscope 
installed, vim will only refuse to issue cscope specific commands. 
>How-To-Repeat:
Compile editors/vim without changing any package options. Try to run a cscope 
command from within vim.
>Fix:
Add --enable-cscope to the default configure arguments in 
editors/vim-share/Makefile.command and remove the cscope options.

There is no dependency on cscope itself, so it could be added without doing any 
harm. If the user really wants to use both, he could easily install cscope 
afterward.
