Direct line continuations

With a vertical slash/pipe character (|) you declare a direct line continuation, whatever you write on that line is also appened to the previous field, but directly and without any spacing inbetween:

Final remark: spaced and direct line continuations can be mixed in any fashion:

\                -o output.hashed
\                --verbose
