By default deft will save a changed buffer that it opens after 1 second.
This causes problematic interactions with the rest of doom - like with
wsbutler (insert space, try to insert a link, and it will eat the
space before the link is inserted).
I think it's best for auto-save to be managed by a separate package,
rather than this ad-hoc save that occurs only in buffers that deft opens.
