[make-mode.el] Infinite loop

Suppose you have a Makefile with the following contents:

FOO = bar \
        xxx/xxx.xx xxx/xxx.xx

If you put the cursor at the start of the second line and type
`M-: (looking-at makefile-dependency-regex) RET' Emacs will enter an
infinite loop.

I noticed this while trying to generate a change log entry for such a
Makefile by doing `C-x v =' and typing `C-x 4 a' with the point on the
changed line in the diff buffer.  Then `makefile-add-log-defun' will
be called which includes the `looking-at' statement mentioned above.
