	# TL;DR:
	# Run helptags doc
	# If an error happens, the try-catch catches it. Echoerr v:exception then logs it
	# and aborts the rest of that command. If it doesn't error, the `qa` is executed,
	# and vim exits normally, resulting in the last -c not being executed.
	# The last -c is only executed if an error occurs, and cq is exiting vim with an error,
	# which causes the CI to observe teh error as well, and causing a proper CI failure.
	# Stonks!
	vim -c "try \| helptags doc \| catch \| echoerr v:exception \| endtry \| qa" -c "cq"
