* doc/find.texi (xargs options): Explain that the logical end of
file marker string set with -E is not special if -d or -0 was
specified.
* xargs/xargs.c (usage): Mention this in the --help output.
(read_string): Correct the function header comment to point out
that there is no logical end-of-file processing for this case.
Also point out that the delimiter may not always be NUL.
This documentation update fixes Savannah bug #36652.
(main): Emit a warning message if -0/-d is specified and -E was
also used.
* xargs/testsuite/xargs.gnu/E_-0.exp: Don't compare stderr output,
since for this case xargs now emits a warning message.
* NEWS: Mention this change.
