for side-by-side, an option for full content (without skipping)

[alicerusso]

Feature request: for side-by-side output, would like to have a "full" option that doesn't skip the matching text.

This option was added to rfcdiff at the RPC's request a couple years ago bc sometimes it's best to review only the changes, while other times "full" document review is better. The output with the full option is better for reviewing editorial issues throughout the document, rather than just the parts that have changes (e.g., when reviewing consistency of a term or figure titles).

From rfcdiff 1.48:
--full) prelines=999999;;

sample output

• from rfcdiff --full
  https://www.rfc-editor.org/v3test/draft-ietf-avtext-lrr-06-07-full-rfcdiff.html (this doesn't contain "skipping" for each portion of matching text)
• from rfcdiff
  https://www.rfc-editor.org/v3test/draft-ietf-avtext-lrr-06-07-rfcdiff.html
• from iddiff
  https://author-tools.ietf.org/diff?doc_1=draft-ietf-avtext-lrr-06&doc_2=draft-ietf-avtext-lrr-07

This can be done on the iddiff command line tool by providing --context-lines 0.
I'll expose this on author tools.
