Version 23 of KJN

Keith Nash, "KJN", occasional user of Tcl/Tk and BLT.

The changes to Wiki markup are now described at Formatting Rules

 # old-style text block, often used for code
 set page1 [hget http://example.com/index.html]
 # uses leading space, which is rendered in the output

# new-style code block, no need for leading space
set page1 [hget http://example.com/index.html]

# new-style text block, no need for leading space
# does expect Wiki syntax
set page1 [hget http://example.com/index.html ]
