Syntax: Line joining with &\
make has a weird rule for line joining in recipes, where the \ is
retained. This is very annoying espcially when writing little scripts
in other languages in recipes. The GNU make documentation suggests
using a `define' block, in which the \ are still necessary, but
vanish. But that separates out the recipe from the rule, and also
demands that the recipe text be given a name.
(Note that .ONESHELL offers an alternative but sadly is not available
on a per-rule basis. This is even less sensible with non-recursive
make, where you might want different directories to have different
settings.)
So, provide &\ which does the other thing, swallowing the newline and
discarding the &\, even in rules.
Add a test case too.
