Bug with css calc() function

[Dahamugo]

The formatter is removing the whitespace before the + operator inside a calc function. This white space is actually required for the rule to work, so this effectivelly breaks it.

Example:
height: calc(100% + 20px);

Turns into:
height: calc(100%+ 20px);

Same here, the formater brake the rule.

Seems to happen with almost every selector.

What I write:
li:hover > ol

When I run Beautify:
li:hover> ol

It doesn't really brake this particular declaration, but it happens with the calc() function too as mentioned above.
