Swaps the lesser used commands here out to the longer key sequences.  It
turns out I write these more often than I look them up for a given tag.

After redesigning the interface to that one a bit.

This... Almost works?

This spits out links in VimWiki syntax, which is more readable and useful
in context than just a raw list of grep results.

(For the grep results, I could always use `gf` to jump to the file, but
it didn't then get added to the VimWiki location list, so the back command
wouldn't work.)

This also uses an sqlite query against an already-built table instead of
pawing through a bunch of files on disk, which is probably faster.

fd is actually pretty nice, btw.

Just a quick index of logs, for the moment.

This is already handled in filter-exec-stdin, using IPC::Cmd, which may
be what I should do here, but I guess this is ok.

I hate pylint so much.

To my surprise, adding --multi was the only thing I had to do here.

Puts tag finding atop screen, fragment menu at bottom.

Adds a preview invocation for fragments.

I worked this out the other night before doing something similar for a
log monitoring utility we use at WMF.

It could use some improvements, and ideally it'd be a general-purpose
utility, but might as well capture this version here.
