Isearch halts in commands and macros

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Binding a "word Isearch" with `C-s C-w' to a shorter command, like
`C-.', causes Isearch to halt.  The unfortunate halting is not
existent in GNU Emacs 20.5.1.

To reproduce, evaluate the following key binding:

  (global-set-key [?\C-.] "\C-s\C-w")

Compare running `C-s C-w' with `C-.'.  I enjoy incremental search's
highlighting of all the instances of the completed search in the
buffer.  If I wanted to halt an incremental search in a key binding or macro 
I'd use `RET'.

  (global-set-key [?\C-.] "\C-s\C-w\C-m")

This behavior exists in the development version of Emacs, also.

Thanks for Emacs,
