Steps to reproduce:

1. Launch neovim with the provided vimrc: nvim -u vim_config
2. Type :w !curl -F' or :e '

At this point the command line should feel noticeably unresponsive.

Thanks for the report! I can reproduce this.

Same problem happens when misspelling env vars, e.g :e $PWDD/

I've pushed ec38c95331a3333f70924031f78c6302813baf1c which should fix this issue.

Could you help verify by pulling the latest master? Thanks!

I've pushed ec38c95 which should fix this issue.

Could you help verify by pulling the latest master? Thanks!

Yup! That fixes the slow env var expansion issue.
