Print symbols with ratio-like names and the associated ratios distinctly. src/ChangeLog addition: 2010-08-15 Aidan Kehoe <kehoea@parhasard.net> * print.c (print_symbol): Escape any symbols that look like ratios, in the same way we do symbols that look like floats or integers. Prevents confusion in the Lisp reader. * lread.c (isratio_string): Make this available even on builds without HAVE_RATIO, so we can print symbols that look like ratios with the appropriate escapes. * lisp.h: Make isratio_string available even if HAVE_RATIO is not defined. tests/ChangeLog addition: 2010-08-15 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el: Test that symbols with names that look like ratios are printed distinctly from the equivalent ratios.
