Request: Git command inherit Neovim's environment variables

[xlucn]

Problem:
I have some use cases where I want to customize git behavior through either user configuration file or environment variables. Then I found git command spawned by "dep" (through vim.loop.spawn) is not affected by any of those methods. After some digging, I found the environment of the git command is basically empty (by looking at /proc/[pid of git command]/environ file). Thus it's ignoring environment variables, and also ignoring user configuration due to lack of $HOME definition.

(The use case is that I would like to use proxy for git, through http.proxy setting or external commands like proxychains)

Expected:
Git command inherits whatever environment variables Neovim has.

I hope this does not require too much extra work for you, possibly is there another API to do this automatically?
