Wrong cursor position with Prism and unix formatting

[jcubic]

This is really edge case, with latest devel version (that fixed prism) if you have prism and unix_formatting and you have string of text with formatting inside (as html entities, like when you show source code of terminal code) cursor position is wrong when you click on the text inside.

Removing unix_formatting fixes the issue.

Expected behavior

prism work with unix formatting if source code have formatting as html entites inside string.

Actual behavior

You can't click on the text inside formatting inside string.

Steps to reproduce

• include both scripts and run:

$.terminal.syntax('javascript');
term.insert(`
$.terminal.defaults.formatters.push(function(string) {
   return string.replace(/([^\`]|^)\`([^\`]+)\`([^\`]|$)/g, '$1[[b;#fff;]$2]$3')
});
`.trim());

It seems that the problem can be resolved with proper ordering of formatters. prism need to be first formatter if used with unix_formatter:

var t = $.terminal.defaults.formatters;
$.terminal.defaults.formatters = [t[2], t[0], t[1], t[3]]

Maybe unix_formatting can be fixed so this ordering is not needed.
