An invalid .editorconfig file breaks PackerSync

[herrbischoff]

I've already opened an issue at https://github.com/wbthomason/packer.nvim/issues/1008, detailing the problem. In the interest of not repeating information, I'm not re-posting it here.

The short summary being, that the presence of an invalid .editorconfig file in the working directory leads to :PackerSync breaking down entirely and leaving Neovim in an unusable state. I believe that either the plugin or the plugin manager (or both) should guard against such exceptions with a sensible error message as opposed to breaking down.

You can reproduce this behavior with an .editorconfig file containing

[site/templates/**.{php]
indent_size = 2

which is clearly invalid because it misses a closing curly brace. When running :PackerSync, the environment breaks down.
