But single backslashes _aren't_ simply removed.  If I try to depend
a file on the file `foo:bar' (this is under Linux, BTW), and tell make

mytarget: foo\:bar,

it tries to find the file `foo\:bar' (without the backslash, it just
dies because it thinks I'm trying to create a percentless pattern rule.)
