calc whitespace not always preserved

[futtta]

An Autoptimize-user has CSS with a calc in it which gets broken. Whereas YUI-CSS-compressor-PHP-port normally preserves spaces, it does not in this case (confirmed using GUI)

Test input;
input { width: calc(100% - (1em*1.5)); }

Expected output:
input{width:calc(100% - (1em*1.5))}

Actual Output:
input{width:calc(100% -(1em*1.5))}

[futtta]

can you try with this commit @rostik ?

[rostik]

@futtta that didnt work, but i did this, not sure if its correct, but it worked

$this->preserved_tokens[] = preg_replace('/([+-]{1})(/','/$1 (/',trim(preg_replace('/\s_([_/(),])/', '$1', $matches[2])));

[futtta]

yeah, had a stupid mistake in my code (forgot re-replacing $calc by $matches[2]) cfr. this commit.
