bug#6220: subword support in isearch-yank-word-or-char

[Masatake YAMATO]

This is not a bug report. This is a request to include my patch to
official emacs tree.


With the patch you can pull a subword as yank text when you do
\C-w in isearch.

(I've submitted this to emacs-devel the last year.

Thanks, I installed your patch (with one small change:
`boundp' instead of `fboundp').
