"Unfortunately this one liner fails to join more than 2 lines (this is left as an exercise to the reader to come up with a one-liner that joins arbitrary number of lines that end with backslash :))."

This is simpler and works for multi lines with backslashes:

awk '/\\$/ { sub(/\\$/, ""); printf "%s", $0; next }; 1' file1
