Revise print_symbol(), never calling is{float,ratio}_string().
src/ChangeLog addition:
2015-05-08 Aidan Kehoe <kehoea@parhasard.net>
* print.c (print_symbol):
Revise this. No longer call isfloat_string() and isratio_string()
on practically every symbol seen; check explicitly for the known
float format in this function, which turns out to be a more
limited and cheap job than you would think.
Also check for integer and ratio syntax in passing.
Use Vdigit_fixnum_map when working out whether a given character
is a digit.
* lisp.h:
Make Vdigit_fixnum_map available generally.
tests/ChangeLog addition:
2015-05-08 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-reader-tests.el:
Check read and print handling of symbols that look like
numbers. In passing, check the read and print handling of the
associated numbers.

\input /home/gd/gnu/doc/texinfo.tex @c -*-texinfo-*- @c %**start of header @setfilename ../../info/back-cover @settitle XEmacs Lisp Reference Manual @c %**end of header . @sp 7 @center @titlefont {XEmacs Lisp} @sp 1 @quotation Most of the XEmacs text editor is written in the programming language called XEmacs Lisp. You can write new code in XEmacs Lisp and install it as an extension to the editor. However, XEmacs Lisp is more than a mere ``extension language''; it is a full computer programming language in its own right. You can use it as you would any other programming language. Because XEmacs Lisp is designed for use in an editor, it has special features for scanning and parsing text as well as features for handling files, buffers, displays, subprocesses, and so on. XEmacs Lisp is closely integrated with the editing facilities; thus, editing commands are functions that can also conveniently be called from Lisp programs, and parameters for customization are ordinary Lisp variables. This manual describes XEmacs Lisp. Generally speaking, the earlier chapters describe features of XEmacs Lisp that have counterparts in many programming languages, and later chapters describe features that are peculiar to XEmacs Lisp or relate specifically to editing. @end quotation @hfil @bye
