5576e2737a Document that the smallest sequences optimization length is 2 
and a sequences value of 1 is considered to be `true` - which
will be set to the default value of 200.

b40d5de69c Change the default sequences limit to 200 to speed up compress. 
Has little or no impact on minification size in the majority of
cases but can speed up rollup builds significantly.

This sequences change also has the beneficial side effect of avoiding
"stack size exceeded" errors on very large input files.

The user is free to alter the sequences limit if they are so inclined.
The previous sequences limit was 2000. 20 is often sufficient.

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

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.

Don't mix strings with directives in output

645626ebe8 Fix docs for keep_fargs 
Compression options `keep_fargs` and `unsafe` were decoupled in v.2.5.0 (commit 5fd1245), so document actual keep_fargs default.

d5138f7467 add --pure-funcs option 
it has the same effect as specifying `pure_funcs` in `--compressor`
option, however it's much easier to use

instead of:

    --compressor 'pure_func=["Math.floor","debug","console.logTime"]'

it's now possible:

    --compressor --pure-funcs Math.floor debug console.logTime

ecfd881ac6 Keep unused function arguments by default 
Discarding unused function arguments affects function.length, which can lead
to some hard to debug issues.  This optimization is now done only in "unsafe
mode".

fbbaa42ee5 Add option to preserve/enforce string quote style 
`-q 0` (default) use single or double quotes such as to minimize the number of
 bytes (prefers double quotes when both will do); this is the previous
 behavior.

`-q 1` -- always use single quotes

`-q 2` -- always use double quotes

`-q 3` or just `-q` -- always use the original quotes.

Related codegen option: `quote_style`.

Close #495
Close #460

Some `yargs` guru please tell me why `uglifyjs --help` doesn't display the
help string for `-q` / `--quotes`, and why it doesn't output the expected
argument types anymore, like good old `optimist` did.
