This has more features than parse_git_branch, though it could use a way
to display the _number_ of untracked / modified files (I'll have to see
if that's available).

I'm not including a copy of git-prompt.sh in the repo.  If it's not
available in the user's home directory, I mock up a function that uses
the old parse_git_branch instead.

This is, in fact, super handy.  I'm pretty sure I got this idea from
reading somebody's config on lobsters, although I'm not exactly sure.

Resetting the prompt was causing weirdness with fzf (and maybe some other
things).  The window title just seems nice to have.

Tyler pointed this out during some pairing session.

Current one leads with timestamp, has an scp-like username@host:path
section, varies prompt character using bin/fragment-bullet.

Trying a 2-line thing again.  I doubt I'll stick with it, but you never
know.

Also clears out some cruft, makes colortest() a little cleaner.

It looks like I went to check whether commandlog was installed a while
back and neglected to actually specify "commandlog" instead of the "foobar"
from the example I was looking at, so commandlog hasn't been running for a
couple of months.

- add zsh syntax highlighting plugin
  - add more color options to prompt configuration
  - tweak inertia prompt colors
  - refresh prompt periodically (this may need some thought)
  - add Alt-Up, Alt-Back for dir navigation
  - automatically rehash to pick up new commands for completion

Use fzf to select files from changed files (including untracked) in a
working tree.  Thanks to @tomasino@mastodon.sdf.org for the git subcommand
idea here - these are scripts rather than aliases, but the interface
is pretty well the same:

It turns out that terminals really can't handle a lot of unicode chars
without freaking out.  Better fonts might help; I'm not honestly sure.

Nothing drastic in this commit; just takes care of some little
inconsistencies and quibbles.  Probably breaks a few files with calls to
filter utilities, but those should be easy to fix on a case-by-case basis.
I'm renaming them because there's nothing vim-specific about them.

- move a few aliases to bin/
  - tags -> build-tags
  - extip -> get-external-ip
- rename some utils in bin/
  - vim-filter-* to filter-*
  - vertical to filter-vertical
- remove some bogus stuff from bin/
  - googleearth
  - d (some thing i was messing around with for menus)
  - pup (nice util, but should install elsewhere)
- add a bin/cheat to hang cheatsheet stuff on
- use fzf-tmux for h alias

I'm not 100% sold yet, but it's basically dmenu for the shell.  Much to
recommend.  Adds an improved ctrl-r.

unsorted-unique is just a wrapper around a short awk operation.  I put it
in its own script because quoting things in aliases is hard.

It's neat; it's too opinionated.

This is way primitive, but I think a full-featured version won't actually
be much more code.

History is still kind of weird with this.  Switches to using scd for
directory history.

Sometimes it's good to be reminded what shell you're in.

Possibly quite slick.

There's probably a better way to do this, but right now it just adds a
chpwd func to .zshrc to tack dirs onto ~/.directory_history.  The h alias
now uses this file instead of the dirs builtin.

I'm realizing that this is all kind of an embarrassing mess, and doing my
best not to cat-vacuum it into a more complicated state.

for some reason i forgot i could override system-wide binaries because the
path is expanded ltr
