copyfilerange: wrap some overlong lines (in a tabsize-independent way)
Most tools in util-linux seem to assume a tabsize of 8, judging from
the alignments of several continuation lines. But `copyfilerange.c`
appears to have assumed a tabsize of 2, because with a tabsize of 8
the text on line 147 started in column 209!
But even with a tabsize of 2, three lines were much wider than the
reasonable 100 columns. So, wrap those, and in the bargain improve
the wording of the affected messages, and add a space before %m.

chmem: fix segfault when parameter is just a dash
When running "chmem --disable -", ul_strv_split("-", "-") returns an
empty array (length 0) because the input string contains only the
separator. The code only checked for length > 2, so length 0 fell
through to parse_range_param() with NULL pointers, causing a segfault

Fix by rejecting parameters that produce fewer than 1 token, and add
NULL checks in parse_range_param() for additional robustness.

lib/pager: Drop less workaround

lib/pager: Do not overwrite LESS environment var
libblkid: (probe) Account for IO bias when retrieving buffer from parent
The 'off' variable gets aligned to 'pr->io_size'. However when
delegating to the parent prober, the value for 'off' from the original
function parameter needs to be used.
Undo the bias before calling into the parent prober.

man: hide LIBSMARTCOLS_JSON in man pages that do not support --json
PR #4070 consolidated libsmartcols env vars into man-common/env-smartcols.adoc
and had all tools (including fdisk and cfdisk) include it. That documented
LIBSMARTCOLS_JSON in fdisk/cfdisk man pages although those tools do not
support --json output, which is misleading.
Use ifdef::smartcols-json[] in env-smartcols.adoc so the JSON env var
section is only rendered for man pages that set :smartcols-json: (column,
lsblk, findmnt, sfdisk). fdisk and cfdisk include the same file but do not
set the attribute, so they only show the debug-related variables.
lib/fileeq: Check arithmetic in ul_fileeq_set_size
Make sure that arithmetics do not overflow data types. Such overflows
could occur with large hardlink options or on 32 bit systems with large
files (due to size_t usage).
If possible, reduce sizes so operations can continue successfully.
