glow -p not working with nvimpager

[Luis-Licea]

Executing glow -p README.md returns an error only whenever nvimpager is set as the PAGER. Setting the pager to most or less -r solves the problem, but is inconvenient because nvimpager works fine for everything else.

glow -p README.md                                                                                           ✔  NORMAL  09:01:51 PM  

All markdown files over a certain length give this error. I attached an example. test.md

I found my way here when trying to understand why I couldn't get a custom theme to work by providing the path to its JSON file.

The default auto or dark settings did render colors fine though, even with nvimpager.

My problem was the custom being silently ignored. After finding this issue, I tried prefixing the glow call with PAGER=less and it worked.

I suppose until #440 is tackled there is no way to force color output and see if that allows nvimpager to render it?
