Filenames with special characters are not supported

[ilian]

Opening files containing the $ character will evaluate part of the filename as an environment variable. Special characters need to be escaped such that they are not interpreted by vim.

How to reproduce

1. Create a file with a name containing the $ character (e.g. $PWD.c).
2. Select the newly created file with ranger.vim to edit.
3. The wrong file has been chosen to edit by ranger.vim, as seen by executing :ls in vim.

Bumping this issue, it's especially dominant in Remix land since they use the splat & character for routing. Would love a solution here :)
