Ref #36. Join a line ending with a backslash with the next line. This joins an arbitrary number of such lines, but breaks (Solaris nawk) at 6144 chars in any merged line.

This works because sub() returns the number of changes it made. No matches is not an error.

awk '{ while (sub (/\\$/, "")) { getline t; $0 = $0 t; } print; }'
