  3. each line in the file is a string of no more than {LINE_MAX} bytes including a terminating <newline> character.
And I have seen awk implementations that ignore incomplete lines.

The wc utility, on the other hand, is defined to work on any file type; not just text files. If you look at the standards, wc -l prints a count of <newline> characters found in a file; not the number of lines in a file.
If we want to be really anal and follow the strict definition of a text file, it may or may not contain a terminator (NL/CR/LF) at the end.

Awk might think differently of course.

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
