0.8.6.39:

	Quiet.  Too quiet.  Fix bug in pprinting backquotes, introduced
	*sigh* when fixing the last bug...
	... we need to print once to a string stream, to look at the
		first character to make sure that it's not a @ or a .
	... and then we need to print again, but this time to the real
		stream (which is at a different logical block position)
	... yes, possibly there is a better way.

	Also put identity where mouth is: add self to SUPPORT
