SHOW positive means print details about the type (e.g. enum values),
and print structure elements passing SHOW - 1 for show.
- SHOW zero means just print the type name or struct tag if there is one.
+ SHOW negative means just print the type name or struct tag if there is one.
If there is no name, print something sensible but concise like
"struct {...}".
- SHOW negative means the same things as SHOW zero. The difference is that
- zero is used for printing structure elements and -1 is used for the
- "whatis" command. But I don't see any need to distinguish.
