[bug#54221] [PATCH 0/4] vim: Detect plugins via search paths.

[seerlite]

Hi! Sorry for the delay, I've been very busy.

I sent the rebased patches but only the bits that added search paths.  There 
were some updates to both Vim and Neovim since I sent the first patch and I 
didn't want to deal with fixing the conflicts and re-understanding the style 
changes I had even forgotten I made. So I'm sending just the functional parts 
of the patch and hopefully someone else can update the package styles if 
necessary :)

Oh and I'd like to remind you of this patch: 
<https://issues.guix.gnu.org/48112> which along with my patch would make it so 
Neovim can finally use both Vim and Neovim-exclusive plugins. I'd appreciate if it 
got merged too.
