Optimization of adjacent (?) blocks and multiple properties.

I think this is bug.

I have a sample CSS code:

.transfers.is-toggle-visible {
  display: block; }

.transfer {
  display: inline-block;
  width: 120px;
  width: 134px;
  width: 140px;
  display: block;
  width: auto; }

This is what I would expect as CSSO output (using whitespaces for clarity):

.transfers.is-toggle-visible {
  display: block; }

.transfer {
  display: block;
  width: auto; }

And this is what I get (added whitespaces for clarity):

.transfers.is-toggle-visible,
.transfer {
  display:block }

.transfer {
  display:inline-block;
  width:140px;
  width:auto}

The original output of CSSO without the added whitespaces:

.transfers.is-toggle-visible,.transfer{display:block}.transfer{display:inline-block;width:140px;width:auto}

(Sorry about the title of the issue - I'm not sure how to name it correctly.)

Yep, there are few bugs actually.

1. display is never merging; it was hardcored, but I fixed it yesterday (see issue Remove duplicate properties #167)
2. width is not merging, because of regression in 1.4, due to emergency solution for wrong value merge that has different browser support. It's not a bug, but compression could be better. I reworking compression algorithms now and declaration merging as well. So it's would be fixed in next release.

Current dev version output is (formatted for readability)

.transfers.is-toggle-visible, .transfer {
  display: block
}
.transfer {
  width: 140px;
  width: auto
}

Correct output should be

.transfers.is-toggle-visible, .transfer {
  display: block
}
.transfer {
  width: auto
}

Great news, looking forward to the next release then. Thanks!
