Keep occ output brackets escaped through the formatters

The overtyping and from_ansi formatters unescape brackets before they
parse the text, so escaping them beforehand was not enough: literal
brackets were still read as formatting. Enable
unixFormattingEscapeBrackets so both formatters escape the text again
after parsing. Verified in the browser: Symfony's "[alias]" in
`occ list` stays in place, ANSI colors still work, and formatting in
the output text (colors, links) is no longer applied.

Bump the version to 0.4.4 so browsers load the new script.
