grep - unexpected behavior with --color

[Adams, Eric A (MN14)]

Hi,

In testing grep-2.5, I saw an unexpected interaction between options --color
and
--word-regexp.

If I use both options, the output highlights all occurances of the target
string,
both whole words and parts of words.

Testcase:

echo "yes no xxyesxx" | ./grep --color -w yes       # highlights two strings
echo "yes no xxyesxx" | ./grep --color '\<yes\>'    # highlights one string

This is either a bug or a feature :)

Thanks for all your work,
Eric Adams.
