kzc 02c638209e Enable --screw-ie8 by default. 
catch identifier is mangled correctly for ES5 standards-compliant JS engines by default.

Unconditionally use the ie8 if/do-while workaround whether or not --screw-ie8 is enabled.

To support non-standard ie8 javascript use: uglifyjs --support-ie8

Anthony Van de Gejuchte 3a7d53f3cf Move OctalEscapeSequence to read_escape_char 
This should simplify and improve implementation, make it easier to
implement template strings, and keep master a bit more in sync with
harmony.

Previous implementation wasn't broken, though the loop gave me the
impression it could read infinite numbers and annoyed me a bit. It was
also slightly unnecessary because the lookup involved only 3 characters.

Anthony Van de Gejuchte dda58244b6 Fixes to prevent failing tests after merging master 
* Add missing quote properties to AST_ObjectKeyVal
 * Avoid test results being interpret as directives
 2016-06-20 15:02:09 +02:00
Shrey Banga e645ba84cf Respect quote style in object literals 
The option added in fbbaa42ee5 wasn't
being respected inside object literals, so quoted property names would
still be stripped out with this option.

This is mostly a corner-case, but useful when the output is passed to
something like the Closure compiler, where quoted property names can be
used to prevent mangling.
