Variable is assigned wrong value

[Sam Ravnborg]

When a variable is followed by a comment the variable is assigned a value
containing a space.

Sample Makefile:
------------------------------
var1 := X
var2 := X # Comment
$(warning var1=-$(var1)-)
$(warning var2=-$(var2)-)

all:
------------------------------
Output:
$make -v

$
$make
Makefile:4: var1=-X-
Makefile:5: var2=-X -
make: Nothing to be done for `all'.

Note that var2 is assigned a value including a trailing space.
