Undocumented PostScript features?

According to the entry on PostScript in Wikipedia,

"...many aspects of PostScript language are not documented at all.
Ghostscript source code is the best reference to undocumented PostScript.
For instance, do you know that Adobe implementations skip '\t', '\r', '\n',
and ' ' after eexec but doesn't skip '\0' or '\f'. So the binary stream
cannot start with some white space characters."

Other than combing through the Ghostscript source code, where could I find
listings of these and other undocumented PostScript implementation features?
