The most intuitive way I can think of is that comment lines are completely
removed except that a trailing backslash prevents the line end.
Thus you could say

fooabr=1\
	2\
#	3\
	4

or in a makefile:

OBJECTS = \
#	foo.o \
	bar.o \
	foobar.o

and the lines beginning with '#' would be silently removed from
the input.
