A more detailed notice is on realloc(3p).
......
$ man 3p realloc \
|sed -n \
-e '/APPLICATION USAGE/,/^$/p' \
-e '/FUTURE DIRECTIONS/,/^$/p';
APPLICATION USAGE
The description of realloc() has been modified from pre‐
vious versions of this standard to align with the
ISO/IEC 9899:1999 standard. Previous versions explicitly
permitted a call to realloc(p, 0) to free the space
pointed to by p and return a null pointer. While this be‐
havior could be interpreted as permitted by this version
of the standard, the C language committee have indicated
that this interpretation is incorrect. Applications
should assume that if realloc() returns a null pointer,
the space pointed to by p has not been freed. Since this
could lead to double-frees, implementations should also
set errno if a null pointer actually indicates a failure,
and applications should only free the space if errno was
changed.
FUTURE DIRECTIONS
This standard defers to the ISO C standard. While that
standard currently has language that might permit real‐
loc(p, 0), where p is not a null pointer, to free p while
still returning a null pointer, the committee responsible
for that standard is considering clarifying the language
to explicitly prohibit that alternative.

In the SYNOPSIS, a long function prototype may need to be
continued over to the next line. The continuation line is
indented according to the following rules:
1. If there is a single such prototype that needs to be continued,
then align the continuation line so that when the page is
rendered on a fixed-width font device (e.g., on an xterm) the
continuation line starts just below the start of the argument
list in the line above. (Exception: the indentation may be
adjusted if necessary to prevent a very long continuation line
or a further continuation line where the function prototype is
very long.)
Thus:
int tcsetattr(int fd, int optional_actions,
const struct termios *termios_p);
2. But, where multiple functions in the SYNOPSIS require
continuation lines, and the function names have different
lengths, then align all continuation lines to start in the
same column. This provides a nicer rendering in PDF output
(because the SYNOPSIS uses a variable width font where
spaces render narrower than most characters).
Thus:
int getopt(int argc, char * const argv[],
const char *optstring);
int getopt_long(int argc, char * const argv[],
const char *optstring,
const struct option *longopts, int *longindex);

Different source styles are used in different pages to achieve the
same formatted output, and in some cases the source mark-up is a
rather convoluted combination of .RS/.RE/.TP/.PD macros. Simplify
this greatly, and unify all of the pages to use more or less the
same source code style. This makes the source code rather easier
to read, and may simplify future scripted global changes.
The feature test macro info is currently bracketed by .nf/.fi
pairs. This is not strictly necessary (i.e., it makes no
difference to the rendered output), but for the moment we keep
these "brackets" in case they may be replaced with something else.

Quoting Heinrich:
The strnlen.3 manpage has the following sentence:
"In doing this, strnlen() looks only at the first maxlen
characters in the string pointed to by s and never beyond
s+maxlen."
This sentence is self-contradictory:
The last visited character implied by "first maxlen
characters" is s[maxlen-1].
Given that "beyond a" does not include "a", the last visited
character implied by "never beyond s+maxlen" is s[maxlen].
A consistent sentence would be
"In doing this, strnlen() looks only at the first maxlen
characters in the string pointed to by s and never beyond
s+maxlen-1."
I would prefer
