    _______________________________________________________

Details:

When target of double-colon rule have characters escaped by backslashes, make
doesn't mark this rule as double-colon.
Simplest example of makefile illustrating the problem is:

a\ b :: ; @echo one
a\ b :: ; @echo two

Output of _make 'a b'_:

Makefile:2: warning: overriding recipe for target `a b'
Makefile:1: warning: ignoring old recipe for target `a b'
two

While the expected output is:

one
two


I'm using GNU Make 3.82 on Gentoo x86_64. Make built from the latest CVS also
has this issue.

After examining the source I made a trivial patch (attached) which fixes this
problem (tested on few projects and as far as I can see it doesn't break
anything).
