Existing implementations do it like the draft suggests, in that when  
they use the Link header, they accept the specified form.

FF3.5 allows both multiple spaces and tabs.
Opera 10b3 only allows multiple spaces, doesn't recognise tabs.
Safari and IE both appear to ignore the Link header.

The safest thing to do is to leave it specified as a single space; all  
implementations that support Link (remembering that it was first  
defined this way in 2068) will be able to consume that.
