* c-typeprint.c (c_print_type_base): Treat show = 0 just like

show < 0.  The only case where we had been distinguishing is that
	show = 0 used to print "struct  " or "enum  " instead of
	"struct {...}" or "enum {...}" which seems clearly wrong.

-   SHOW nonzero means don't print this type as just its name;
-   show its real definition even if it has a name.
-   SHOW zero means print just typename or struct tag if there is one
-   SHOW negative means abbreviate structure elements.
-   SHOW is decremented for printing of structure elements.
-
-   LEVEL is the depth to indent by.
+   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.
+   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.
+
+   LEVEL is the number of spaces to indent by.
    We increase it for some recursive calls.  */
