bugfix for external_file links containing :linenumber

[laher]

Currently when you link to an external file like {/ file.txt:123}, it opens a file named file.txt:123 instead of file.txt on line 123.

This addresses it, but there are 2 (related) workarounds here - see comments. I'd appreciate any help with eliminating them.

My first neorg PR. Ta

So it seems the workaround is needed (or some similar workaround), for now, due to a neovim inconsistency between nvim_command and nvim_cmd/nvim_parse_cmd.

vim.api.nvim_command('edit +1 index.html') -- this works
vim.api.nvim_cmd(vim.api.nvim_parse_cmd('edit +1 index.html',{}),{}) -- this opens "+1 index.html”

See neovim/neovim#23782 . Thanks @champignoom

Ha, it looks like this has been superceded by a broader fix in this PR: #903

I'll close this for now & see how it goes with the other PR
