There's nothing quite like finding a stupid bug in your stupid code you
wrote when you were like 20.

Anyway this turns out to be a nearly-pointless micro-optimization, but in
principle I think it's not wrong.

Stupid.

This reverts commit 4767c623c7.

Something is broken - only rendering a single year.

It appears to be a _lot_ faster to check "is a regular file" (knowable
just from stat, presumably) than a heuristic for "is ASCII or UTF-8", and
it's completely reasonable to treat regular files matching entry patterns
as markup blobs.

This whole sub is gross.

Really HTML::Entities should be exposed to templates and used there,
sorta like SparkLib\Template offers $h().

Can be a lot, with a big archive.

...mostly what this does is override the defaults of no headers / no
smartypants features.

Just does an inline substitution for <textile> and <markdown> stuff.

Also adds a bit of commentary.

- strip HTML::Defang
- get rid of old wala markup code
- use Discount for both markup modules (with NOHTML flag in wala)

...also test that it'll render a snippet.

Start using top-level headers for entry files.

...plus random whitespace changes.

Moar memory, less potential confusion doing it in place.

Also made it send errors to the log instead of displaying them.

Never really did anything with the idea.

Sometimes it becomes painfully obvious that you never ran the tests.

This is cheesy, probably XSS vulnerable, and some things are still broken.
