Template:Convert/Dual/LoffAonDxSflip

The Template:Convert/Dual/LoffAonDxSflip converts a range of numbers, reversing the input range to be the output, while displaying custom separators around the output amounts, with abbr=on to show the unit symbols. Examples:
 * 4 - 6 cm &rarr; 4 - 6 cm
 * 4 - 6 cm &rarr; 4 - 6 cm
 * 3 - 7 km. &rarr; 3 - 7 km
 * 2 - 5 m &rarr; 2 - 5 m

This subtemplate is invoked from whichever range-word subtemplate is used, such as Convert/- or Convert/to (etc.), passing the output unit-code parameter {5} as {4} here, and passing parameters {6} & {7} as being parameters {5} & {6} here.
