[issue21284] IDLE reformat tests fail in presence of non-default FormatParagraph setting

[Raymond Hettinger]

New submission from Raymond Hettinger:

When a user sets FormatParagraph to anything other than 70,
test_idle.py has 4 failing tests:

test_comment_block (idlelib.idle_test.test_formatparagraph.FormatEventTest) ... FAIL
test_long_line (idlelib.idle_test.test_formatparagraph.FormatEventTest) ... FAIL
test_multiple_lines (idlelib.idle_test.test_formatparagraph.FormatEventTest) ... FAIL
test_short_line (idlelib.idle_test.test_formatparagraph.FormatEventTest) ... FAIL

The solution is to make these tests setup by:
  1) save the user's default configuration
  2) set the paragraph reformat width to 70
and tear-down by:
  1) restoring the user's default configuration
