Update of patch #3962 (project grep):
Status: None => Done
Open/Closed: Open => Closed
_______________________________________________________
Follow-up Comment #3:
Applied as CVS revision 1.7 of "tests/foad1.sh".
For posterity, given the input and pattern strings, and the --ignore-case
flag, POSIX implies that:
- this logic is wrong: if (lc(input_wchar) == lc(pattern_wchar)) ...
- this logic is wrong: if (uc(input_wchar) == uc(pattern_wchar)) ...
- this logic is right (but could be optimized): if (input_wchar ==
pattern_wchar || lc(input_wchar) == pattern_wchar || uc(input_wchar) ==
pattern_wchar) ...
Study the new tests to understand how this does make a difference.
