Merges mvcLineLengthDialogs.1.cs

https://lists.squeakfoundation.org/pipermail/squeak-dev/2022-April/219789.html

Adds a line-length limit to MVC dialogs. Complements Morphic-mt.1935. Due to the recent elimination of #withCRs in many places, this change has been overdue for an even longer time.

Example (to be run in an MVC project):
    self inform: Object comment

  	Answer the index of the current selection, or zero if the mouse is not released over  any menu item. Location specifies the desired topLeft of the menu body rectangle. The final argument indicates whether the menu should seize the keyboard focus in order to allow the user to navigate it via the keyboard."
