cut: fix handling of overlapping ranges
This issue was introduced in commit v8.21-43-g3e466ad
* src/cut.c (set_fields): Process all range pairs when merging.
* tests/misc/cut-huge-range.sh: Add a test for this edge case.
Also fix an issue where we could miss reported errors due
to truncation of the 'err' file.
