add support to less functions paramters braces

[lejenome]

this PR adds better support for less functions braces (no new lines between function parameters)
e.g: the new code outputs this

.box-shadow(@shadow: 0 1px 3px rgba(0, 0, 0, .25)) {
    -webkit-box-shadow: @shadow;
    -moz-box-shadow: @shadow;
    box-shadow: @shadow;
}

and the old code outputs this:

.box-shadow(@shadow: 0 1px 3px rgba(0,
0,
0,
.25)) {
    -webkit-box-shadow: @shadow;
    -moz-box-shadow: @shadow;
    box-shadow: @shadow;
}

"Round brace"... do you mean parenthesis?

[lejenome]

yes

[bitwiseman]

Let's call them that then. 😄
You can say call it parenLevel if you like. roundBraceLevel is odd.

[lejenome]

ok done

[bitwiseman]

Thanks for the PR. You have tests and updated python, too. Very cool.
Naming question... And I need to look at it a little more closely before merging.

[lejenome]

There is a test not supported yet. given:

.tabs   ( ) { }

the code will output (1 space between function name and parenthesis)

.tabs () {}

instead of

.tabs() {}

Is it just me or does it look like the build failure was unrelated to the changed code? Did Travis just flake out?

[lejenome]

It's an error on node's npm, unrelated to js-beautify code

[bitwiseman]

@lejenome - I've merged your change. Thanks!

It turned on the test you said was failing, just to encode the behavior. It might be incorrect but it isn't horrible or a syntax error. We can address it later. Please file an issue.
