When vim-plug installs a new plugin, .git/config looks like this:
[core]
...
[remote "origin"]
url = https://git::@github.com/justinmk/vim-matchparenalways.git
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
...
The
url = https://git::@github.com/justinmk/...
fragment seems unusual. I would expect it to be
url = https://github.com/justinmk/...
With git::@github.com, I cannot git push changes. Replacing it with github.com allows me to push changes.
I'm assuming this is due to a git setting or one of vim-plugin's particular git invocations, but before investigating I thought I would ask if this happens for others. It happens for me on Windows/OS X/ubuntu.
