They hypothesis behind this change is that the undo is undoing an edit that came before, not the temporary edit that appears in insert-close-paren. So, when there are no edits happening (ie when fixup? is #f) then don't undo. This is only a hypothesis because we were not able to find a small code sequence, outside of DrRacket to cause the bad behavior, so possibly there is really more going on here. Thanks to Nadeem Abdul Hamid for finding this fix. Closes PR 13454 |

The Racket Programming Language =============================== Instructions for building Racket from source are in src/README. The main executables in this package: * DrRacket: Racket's integrated development environment (start here!). * racket: command-line tool for running Racket programs. * raco: command-line tool for compilation, documentation, and more. More Information ---------------- For Racket documentation, use DrRacket's `Help' menu, run the `Racket Documentation' application (Windows or Mac OS X), or run `raco docs' from a command line.
