[bug #23920] find.1: please add short note about no trailing slashes for directories

[Eric Blake]

Follow-up Comment #5, bug #23920 (project findutils):

Oops.  I was thinking that -path added an implicit leading and trailing *,
but that is not the case.  Just like -name, the pattern does not match an
internal substring unless explicit globs are provided.  So, revisiting the
examples:

$ find 2008/ 2001/ -path 2008/ -o -path 2001
2008/
$ find 2008/ 2001/ -path 2008/ -o -path '2001*'
2001/
2008/
$ find 2008 2001 -path 2008/ -o -path 2001
2001
$ find ./src/emacs/ -path ./src/emacs/
./src/emacs/
$ find . -path ./src/emacs/
$ find . -path './src/emacs/*'
./src/emacs/foo.c

So, indeed, a trailing slash to path will never match anything except command
line arguments, making it almost worthless for -prune.
