Breaks on macOS/BSD: non-portable split options

[ches]

Hi, thanks for this plugin.

Unfortunately as the title says, it breaks on macOS/BSD because of the usage of split:

vinfo/autoload/vinfo/repo.vim

Line 35 in 3471cd5

exe 'silent !split -l 5000 -d --additional-suffix .txt ' . l:doc . ' ' . l:doc_path . a:doc

The -d and --additional-suffix flags are GNU-specific, they're not POSIX and not in BSD split.

Hi, Because info is primarily a GNU/Linux thing I didn't bother to make it compatible with other systems, lately I've bee using FreeBSD and MacOS though so I will fix this. Thanks for letting me know

Do we think requiring coreutils for macos is a solution to this? It can be installed via brew:

brew install coreutils

If so, I can make a PR.

That's the PR for MacOS. It's pretty naive and doesn't really address BSD
