# It is a common style to align the continuation backslashes at the right
# of the lines, usually at column 73.  All spaces before the continuation
# backslash are preserved and are usually outside a shell word and thus
# irrelevant.  Having these spaces collapsed makes sense to show the command
# in its condensed form.
