octave: libinterp/corefcn/error.cc annotate

annotate libinterp/corefcn/error.cc @ 27746:ae821ac9ec74

Change warning to be case insensitive about options (bug #57290). * error.cc: Add "#include <algorithm>" to list of includes. * error.cc (Fwarning): Use std::transform atd tolower to lower case first argument (arg1). Add new variable "arg2_lc" which is a lowercase version of arg2 (option). Add new variable "arg3_lc" which is a lowercase version of arg3 ("local"). Change relevant comparisons to arg2_lc and arg3_lc. Add BIST test for bug #57290.
