typing perl regexp word boundary into google turns up 
lots of things eg:
http://www.comtech-pcs.com/regexp.html

Perl defines the following zero-width assertions: 


    \b  Match a word boundary
    \B  Match a non-(word boundary)
    \A  Match only at beginning of string
    \Z  Match only at end of string
    \G  Match only where previous m//g left off

A word boundary (\b) is defined as a spot between two characters that
has a \w on one side of it and and a \W on the other side of it (in
either order), counting the imaginary characters off the beginning and
end of the string as matching a \W. (Within character classes \b
represents backspace rather than a word boundary.) The \A and \Z are
just like "^" and "$" except that they won't match multiple times when
the /m modifier is used, while "^" and "$" will match at every internal
line boundary.



\b is what you want for this problem......

sed, ed,  emacs, etc have had \b since the dark ages.
