 	(Multiple Lines): Note that POSIX seems to require \n as
 	separator for all values of FS, but that in reality it
 	doesn't apply to regexps; this is a POSIX bug.

+	after the program text is placed into ARGV and not
+	parsed for options. Thanks to Neil Ormos <ormos-gnulists17@ormos.org>

      'awk' has never behaved that way, nor has 'gawk'.  This is
      essentially a bug in POSIX.
 
-     The original motivation for this special exception was probably to
-     provide useful behavior in the default case (i.e., 'FS' is equal to
-     '" "').  This feature can be a problem if you really don't want the
-     newline character to separate fields, because there is no way to
-     prevent it.  However, you can work around this by using the
-     'split()' function to break up the record manually (*note String
-     Functions::).  If you have a single-character field separator, you
-     can work around the special feature in a different way, by making
-     'FS' into a regexp for that single character.  For example, if the
-     field separator is a percent character, instead of 'FS = "%"', use
-     'FS = "[%]"'.
-
-     Another way to separate fields is to put each field on a separate
-     line: to do this, just set the variable 'FS' to the string '"\n"'.
-     (This single-character separator matches a single newline.)  A
-     practical example of a data file organized this way might be a
-     mailing list, where blank lines separate the entries.  Consider a
-     mailing list in a file named 'addresses', which looks like this:
-
-          Jane Doe
-          123 Main Street
-          Anywhere, SE 12345-6789

-          Records are separated by runs of blank lines.  When 'FS' is a
-          single character, then the newline character always serves as
-          a field separator, in addition to whatever value 'FS' may

-     'RS == REGEXP'
-          Records are separated by occurrences of characters that match
-          REGEXP.  Leading and trailing matches of REGEXP delimit empty
