Hi,

while browsing the sources of `make-mode', I noticed that the variable
initialization of `makefile-browser-client' is wrong. It is
initialized with its documentation string.  This is not a really a
problem, the makefile browser still works, but the documentation
string is lost as soon as the browser is opened once.
