Subject: No shorthand compacting for less than 3 properties.
X-Git-Url: https://git.ndcode.org/public/gitweb.cgi?a=commitdiff_plain;h=5423f4c5955e0335958b012d80e31a8c50bb8f6b;p=clean-css.git

No shorthand compacting for less than 3 properties.

There is no shorthand for 2 properties so there is no way it may
shorten the content.

It speeds up processing by ~5%.
