Describe the bug

$ gh --version
gh version 1.9.2 (2021-04-20)
https://github.com/cli/cli/releases/tag/v1.9.2

When displaying issue comments containing blockquotes, linewrapping of the quoted text is bugs. Long lines (over 72 characters?) have their last word or so printed on the subsequent terminal line, sans the box drawing character used for indentation.

Steps to reproduce the behavior

gh issue view -R cli/cli -c 359, for me the comments from joshriplett on Feb 12 2020 and from me on April 22 2021 exhibit the issue in the blockquotes in those comments.

Expected vs actual behavior

Expected: blockquoted paragraphs wrap attractively.

Actual: long lines take up an 'extra' line in the output.

Logs

Here's an illustration of what I get in my terminal, in case this is not universally reproducible:

silby • 19h • Newest comment


  │ What about the reverse? Quote the entire patch file, and have people
  insert
  │ their comments without the quote marks. That will be familiar for anyone
  │ used to reviewing patches by email, and the  >  prefix on every line
  should
  │ prevent editors from attempting to fiddle with the patch.

  I strongly cosign this suggestion!
