This involves changing grepprg, running, and then changing it back.

Not entirely optimal, but the location window has some good features.

Changes notes-links-for output to match (ish) grep format.

This is incredibly specific to my vimwiki setup at the moment.  It'll
probably expand to include other things, but I decided to just jam it into
one nice generic top-level namespace for now.

...instead of -m.

- changes various BPB_Foo functions to s:FOO, which is cleaner and does
    less trampling on the global namespace

  - adds some vimwiki log / link utilities based on an SQLite db I'm
    building elsewhere

  - comments slightly clearer about how unlikely this is to work for most
    users

  - removes some cruft, including an experimental scratch wiki

Namely log grepping for the more-atomic logs I'm experimenting with and
a calendar lookup fragment.

Renames fragment-vw-diarylink.

In shell and grep.  Awful.  Sort of works.  Still awful.

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

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

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.

...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

Complements the existing f-to-c.

These were playing heck with some terminal environments.

Uses pngphoon and i3lock.

Zap duplicate entries in ~/.directory_history (leaving most recent in
place).

Adds a menu for grabbing input from bin/fragment-*.  Adds a couple of
new fragments, and moves today → fragment-today.

This needs work:

  - it's remarkably slow
  - it has an external dependency in FZF
  - I'm not sure about the keybindings
  - it removes a couple of bindings I'm really used to
  - it's not documented with "CUSTOMIZE" markers
  - this only works in gvim with a recent build of vim 8.1

It might be better if the fuzzy-finder were vim-native, if it
distinguished between full-on document templates and small fragments, etc.

I'm also starting to think it'd be good to compartmentalize some of this
config.

This takes care of everything in the session being able to see the correct
$PATH material - I'd been fiddling with .profile, which is arguably where
this ought to live, but I don't think my prepend_to_path() is valid for
/bin/sh?  I'll probably tidy this up later, but at any rate it solves a
bunch of problems.

Also enables the deletion of bin/firefox-wrapper.

Switch this up for sorting purposes.

Uses date(1) to parse a given date and use it for the header (by way of
bin/today) instead of just defaulting to current date.

This way the template is accurate when opening other diary dates from
the calendar.

Uses xautolock and i3lock.

It turns out that you can use `:0r !foo` to avoid the blank line I was
deleting in BPB_DiaryFragement() and BPB_DatestampHTML().

Also remove a commented-out YouCompleteMe install.
