Editor stuck when some conditions are incomplete

[SOF3]

Steps to reproduce:

1. Create a new file nvim Earthfile
2. Start typing:

VERSION 0.8

foo:
    WAIT

Upon sending T to the terminal, nvim is stuck and does not respond until sigtermed.

If you check the memory usage I bet it'll be 100%.

I noticed this happening with IF statements. The second I hit space after typing IF it hangs and will use 100% memory until you or the OS kills it.
