It probably doesn't matter what's passed in in this case.

- commentary
  - some stuff for "log" entries in vimwiki

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.

...since this isn't a thing any more.

nvim is totally horked on this system at present.

Use SSH instead of HTTPS endpoint.

Finally stopped working - the Boulder Valley School District "improved"
its site.  It was a pretty good run, all things considered.

I keep forgetting to use this.

I really don't know if this is doing anything or not.

- tweak F7 binding for $MYVIMRC weirdness
  - re-add variants of ,td and ,tD bindings because they're easy to use
    for grabbing dates in logging stuff
  - conditionalized clipboard config for neovim
  - p1k3 now lives at ~/workspace/p1k3 by default
  - back to iceberg for color scheme again I guess?  I'm dissatisfied
    about colorschemes.
  - add rust.vim
  - turn gitgutter back on

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.

(Which now means exa, if it's available.)

...for Gerrit remotes, of which there are a lot in my life these days.

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

...silence a warning, quote ssh-agent results.

- Adds a P1K3_ROOT environment variable, and a default of
    ~/workspace/p1k3 (this is new)
  - allows exa for ls aliases
  - Tweaks h() history length a bit

This didn't used to work.  I assume that either some upstream bug has been
fixed or something else in my environment has changed.

Complements the existing f-to-c.

Updates version of VOom, which I haven't really used but may at some point.

Fixes some weirdness with embedded syntaxes in vimwiki by commenting out
the config for specific embedded syntaxes - this should be redundant anyway
since it's auto-detected.

As best I remember, this proceeded from some IRC conversation.

Tyler pointed this out during some pairing session.
