$ sequences in special variable values are mangled by preProcessTemplateBody #184

wrapInQuotes in preProcessTemplateBody writes the quoted line back with:

definitionsBlock = definitionsBlock.replace(firstMatch, wrappedString);

When the replacement is a string, String.prototype.replace treats $$, $&, $` and $' as special patterns. So a $ sequence in a special variable value is rewritten before the frontmatter is parsed.

---
template_title: Budget $$ report
---

creates a note titled Budget $ report, and

---
template_title: Price in $& dollars
---

creates a note titled Price in template_title: Price in $& dollars dollars, because $& inserts the whole matched line.

Passing a function instead, definitionsBlock.replace(firstMatch, () => wrappedString), inserts the string as is.
