RFR: 8332858: References with escapes have broken positions after they are transformed [v2]

[Jan Lahoda]

> If the javadoc comment contains a (Markdown) link like:
> 
> [java.util.Arrays#asList(Object[])]
> 
> 
> The transformer that converts this link into the Javadoc link will not find the reference, as it is looking for `java.util.Arrays#asList(Object[])` (note the missing escapes), which is not present in the original text.
> 
> This patch tries to fix that by permitting optional escapes for all escapable character when searching for the reference, in case the literal search fails. This is done using regexp, although could presumably be done using a manual search.
