changed in include/c.h and applied via sed:
sed -i 's/fprintf.*\(USAGE_MAN_TAIL.*\)/printf(\1/' $(git ls-files -- "*.c")
sed -i 's/print_usage_help_options\(.*\);/printf(USAGE_HELP_OPTIONS\1);/' $(git ls-files -- "*.c")

Consolidate --help and --version descriptions. We are
now able to align them to the other options.
We changed include/c.h. The rest of this patch was
generated by sed, plus manually setting the right
alignment numbers. We do not change anything but
white spaces in the --help output.

This patch is trivial and changes nothing, because
we were always using usage(stdout)
Now all our usage() functions look very similar. If wanted we
could auto-generate another big cosmetical patch to remove all
the useless "FILE *out" constants and use printf and puts
rather than their f* friends. Such patch could be automatically
synchronized with the translation project (newlines!) to not
make the translators sick.

text-utils/tailf.c:69:21: warning: Using plain integer as NULL pointer
Since many 'struct option' has used zero as NULL make them more readable in
same go by reindenting, and using named argument requirements.

Compiling util-linux with musl and uClibc-ng toolchains when wide-char
support is not enabled in ncurses results in compilation failures with
the following message:
error: two or more data types in declaration specifiers
#define
wchar_t char
The problem occurs because util-linux #defines its own wchar_t (as char)
when configured without widechar support. This conflicts with definition
of wchar_t contained in stddef.h.
This error can be reproduced running "<toolchain-cc -o test test.c" with
the following test program:
#include <ctype.h>
#define wchar_t char
#include <stddef.h>
int main()
{
return 0;
}
The only way to avoid the problem it to reorder the inclusion of headers
in some files under the text-utils directory.

The current default is to print all usage() output. This is overkill
in many case.

Some inputs make getwc(3) not to progress file descriptor and neither to
report EILSEQ. Detect such situation and skip the bad input.

This implementation aims to be easier to read, more robust dealing all sorts
of unexpected inputs, and possibly even more correct. The correctness
refers to last line handling this implementation does differently than the
previous. With the previous last line that ended to EOF without \n was not
printed.
