good idea

It sounds like bad idea to rush this change. An identifier without spaces is 
easy grep.
If you use shorter ones and if those words are repeated else where in the 
debug log it would be hard to grep too. IKE_AUTH on its own may sound good.  
However, when searching IKE_AUTH there are other matches in debug log it.
That makes it harder to grep and count etc.

example "exchange type: ISAKMP_v2_IKE_AUTH (0x23)"

make a proposal, make full proposal with state stories and other related 
bits text we need. Otherwise it feels we will keep changing too many times. 

This is where we got stuck in the last iteration of such a similar attempt.
