[doc] Expand/cross-ref MD5 commands, tweak anchors to avoid added spacing

Browse Source 
2006-07-28 Paul Jakma <paul.jakma@sun.com>

	* main.texi: link-detect works on Solaris too.
	* ospfd.texi: Twiddle around with anchors a bit more.
	  Clarify how setting MD5 auth by area and by interface interact,
	  and add cross-references, as well as to the required
	  command for setting key material.

address of the router, but need not be - it can be any arbitrary 32bit
