Subject: [PATCH 207/224] find: improve warning diagnostic for the -name/-iname
with '/' in pattern
* find/parser.c (check_name_arg): Add parameter ALT for the alternative
option to suggest. Avoid confusing quoting in the warning by making
the message more terse.
(parse_iname): Pass "-iwholename" as alternative parameter.
(parse_name): Pass "-wholename" as alternative parameter.
