Subject: [PATCH 1/3] maint: sort.c: deduplicate code for traversing numbers
* src/sort.c (traverse_raw_number): New function for traversing numbers.
(find_unit_order): Use traverse_raw_number() instead of open-coding it.
(debug_key): Likewise.

Subject: [PATCH 2/3] sort: make -h work with -k and blank used as thousands
separator
* src/sort.c (traverse_raw_number): Allow to skip only one occurrence
of thousands_sep to avoid finding the unit in the next column in case
thousands_sep matches as blank and is used as column delimiter.
* tests/misc/sort-h-thousands-sep.sh: Add regression test for this bug.
* tests/local.mk: Reference the test.
* NEWS: Mention the bug fix.
Reported at https://bugzilla.redhat.com/1355780
Fixes http://bugs.gnu.org/24015
