Currently just a wrapper for `bc -ql`.

I was tired of thinking I'd come up with a tag but not being able to find
it in the existing page set.

There's some glitchiness here.

They added a bunch of extra links to the thing I was just dumping out
in Lynx, so I decided to check if there's an easy enough API to work with.

I don't really remember why I wrote this.

A very me-specific task grepper for vimwiki.

Saves some keystrokes on importing to wiki.

Uses git-diff-index.

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

This just wraps the older calendar(1) invocation for the moment, just
adding a layer of indirection so it can include other data.

In case this becomes a module.

For querying overall page list.
