doc: more indexing fixes in manual

* doc/coreutils.texi: Add missing anchors.
* src/pr.c (Usage): Adjust to use -COLS, to avoid a clash
with the additional anchor added to the manual.
Also markup the --columns option as done for other options.
* tests/split/line-bytes.sh: Also fix --lines-bytes typo here.
