The Makefile syntax is tricky wrt whitespace, and target names can
include colons, definitely on MS-Windows, but also on Posix systems.
Also, there are various old formats, like that of Imakefile, that
should still be supported, AFAIK.  And we don't have a test suite for
this mode.  So I very much wonder whether this change will introduce
regressions.

Maybe Paul Smith, the maintainer of GNU Make (CC'ed), could help us
here.  Or maybe Stefan has comments?  For their convenience, I
re-attach the proposed patch below.

Thanks.
