Use \ for Fluent.match(char) and Fluent.match(String)

[numeralnathan]

Currently, Fluent.match(char) will take the character (e.g. $) and wrap it with \Q and \E (e.g. \Q$\E). This is harder to read than \ (e.g. \$). Please make Fluent.match(char) smart in that it will add \ only when necessary.

Furthermore, please make Fluent.match(String) smart in that it will add \ for each character that needs it and if there are 5 or more characters in sequence that need escaping then use \Q and \E. Why 5 or more? To minimize the total length of the regular expression. Adding \Q and \E adds 4 characters. If there are 4 or less characters needing escaping, then adding 4 or less \ will be easier to read.

This will make it easier for humans to read the regular expression.
