sort: use long doubles for general numeric mode
* src/sort.c (general_numcompare): Use long doubles unconditionally, and strtold when available, to convert numbers with greater range and precision. Performance was seen to be on par with standard doubles. * doc/coreutils.texi (sort invocation): Amend the -g description to mention long double rather than double, and strtold rather than strtod. * src/getlimits.c (main): Output floating point limits for use in tests. * tests/misc/sort-float: A new test to ensure sort is using long doubles when possible, and that locale specific floats are handled. * tests/Makefile.am: Reference the new test. * tests/test-lib.sh (getlimits_): Normalize indenting. * NEWS: Mention the new behaviour. Reported by Nelson Beebe.
