Add ascii-case-table, #'with-case-table; make iso8859-1.el more comprehensible. 2007-12-30 Aidan Kehoe <kehoea@parhasard.net> * subr.el (with-case-table): New. Idea and implementation taken from GNU's code of April 2007, before GPL V3 was implied. Thank you GNU. * iso8859-1.el (ascii-case-table): New. Idea taken from GNU. * iso8859-1.el : Change Jamie's implicit compile-time call to a macro literal into something comprehensible to and maintainable by mortals, using to cl.el's #'loop. * iso8859-1.el (ctl-arrow): Initialise it to something more comprehensible.
