Make sure metadata values are treated as strings,
and properly escaped.

```
% pandoc -t markdown -s -M title="<this> *that*"
ok
^D
---
title: \<this> \*that\*
---

ok
```
Escape MetaString values (as added with --metadata flag). Previously they would be transmitted to the template without any escaping. Note that `--M title='foo'` yields a different result from --- title: foo --- In the latter case, we have emphasis; in the former case, just a string with literal asterisks (which will be escaped in formats, like Markdown, that require it). Closes #3792. 2017-08-13 05:25:08 +02:00			`Make sure metadata values are treated as strings,`
			`and properly escaped.`

Markdown writer: fewer unneeded escapes for `#`. See #6259. 2021-05-16 21:23:34 +02:00			`title: \<this> \that\`
