Subject: Add TABDLY, TAB0, TAB3 for better source compatibility.
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=a048a7f6f37f83eb9a0e1ae6d46be0666e46cc07;p=openbsd

Add TABDLY, TAB0, TAB3 for better source compatibility.
These are XSI extensions but some code seems to expect them.
We don't currently implement TAB1 or TAB2.  Idea from FreeBSD.
