how do you plan to remove the spaces?  Do you plan to write something
like $(DEFS)$(DEFAULT_INCLUDES)$(INCLUDES)$(AM_CPPFLAGS) and try to
ensure that each of the variables, if nonempty, starts with a space?
That would make the makefile ugly.

I heard there are filters which can do fancy thinks with the make
output; they were often recommended to people requesting less
verbose output.

I believe these filters are an adequate tool if you want to eliminate
extra spaces and duplicate -I options.

I recognize there is slight difference: the wrapper changes what you
see, but the compiler still gets the option multiple times.  But I
think it is reasonable to suppose that it won't affect the function
of the compiler.

I understand the need for prettier compile commands, and I appreciate
the effort.  But if the prettier ``surface'' means the inner coding
becomes more cryptic, it's not worth it, IMHO.
