They added a bunch of extra links to the thing I was just dumping out

Uses middot for tab extents, and an extends/precedes for stuff that goes
off the screen.

I don't think this works the way you'd want.

This is useful for performance reasons at times.  Folding code is super
slow.

A very me-specific task grepper for vimwiki.

Inspired by a bit of fediverse discussion today that mentioned the
preview pane.

Saves some keystrokes on importing to wiki.

Uses git-diff-index.

Also adds `git ec` alias so maybe I remember to use this.
