Move sh examples onto multiple lines
Move sh examples onto multiple lines

This commit moves shell script examples onto multiple lines and makes
the line-length across the file consistent with Archivematica
guidelines. URLs have been converted to reference-style where they
cannot fit on a single line.

Corrects the --delete-on-complete argument missed during review of
PR #44.
