Opps... Sorry! That should read 'M-<'.
And the TAB's should read SPC.
The correct recipe is:
M-<
C-M-% \b RET foo RET SPC SPC
U
;; All 'foo' keep there :-(
This happen because the regexp "\b" has any printable character.
If we try instead:
M-<
C-M-% is\b RET foo RET SPC SPC
U
;; Now all 'foo' are gone :-)
