Change integer to fixnum in a few places where it wasn't possible mechanically. src/ChangeLog addition: 2011-10-09 Aidan Kehoe <kehoea@parhasard.net> Do a couple of non-mechanical things that would otherwise have been included in the last change. * data.c: * data.c (Ftype_of): Return Qfixnum for fixnums, not Qinteger. * lisp.h (MOST_POSITIVE_FIXNUM): Delete an obsolete comment here. man/ChangeLog addition: 2011-10-09 Aidan Kehoe <kehoea@parhasard.net> * internals/internals.texi (Top): * internals/internals.texi (Authorship of XEmacs): * internals/internals.texi (Modules for Other Aspects of the Lisp Interpreter and Object System): * internals/internals.texi (Introduction to Writing C Code): * internals/internals.texi (Working with Lisp Objects): * internals/internals.texi (Adding Global Lisp Variables): * internals/internals.texi (The XEmacs Object System (Abstractly Speaking)): * internals/internals.texi (How Lisp Objects Are Represented in C): * internals/internals.texi (Allocation of Objects in XEmacs Lisp): * internals/internals.texi (Introduction to Allocation): * internals/internals.texi (GCPROing): * internals/internals.texi (mark_object): * internals/internals.texi (sweep_bit_vectors_1): * internals/internals.texi (Fixnums and Characters): * internals/internals.texi (Future Work -- Unicode): Say fixnum rather than integer when specifically talking about fixed-width Lisp integers.
