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,`

Be less aggressive about using quotes for YAML values. We need quotes if `[` or `{` or `'` is at the beginning of the line, but not otherwise. 2020-10-08 19:54:16 +02:00			`title: \<this\> \that\`
