Wrap Lines ST4 regression

[gerardroche]

The Wrap Lines command, since 4061, wraps entire blocks or "paragraphs". Previously if text was selected the wrap lines command only wrap the selected text, otherwise it would wrap the paragraph.

The API command is wrap_lines.

In the UI it's Menu > Edit > Wrap > Wrap Paragraph at Ruler.

Steps to reproduce

Set a wrap small wrap width to make it easier to test:

>>> sublime.active_window().active_view().settings().set('wrap_width', 5)`

Make a selection (where |...| is the selection):

  xx xx xx
  a1 |a2 a3|
  x1 x2 x3
  b1 b2 b3

Run the wrap lines command:

>>> sublime.active_window().active_view().run_command('wrap_lines')

Expected behavior

The wrap_lines commands should only wrap the selected text, not the entire paragraph.

  xx xx xx
  a1
  |a2
  a3|
  x1 x2 x3
  b1 b2 b3

Actual behavior

The wrap_lines wraps the entire block, instead of just the selection.

  xx
  xx
  xx
  a1
  |a2
  a3|
  x1
  x2
  x3
  b1
  b2
  b3

Environment

• Sublime Text Build: >=4061
• Operating system and version: Ubuntu 18.04...20.04

I can only assume that this was a more or less intentional change.
