            Bug ID: 372250
           Summary: readline's history search on up/down arrow keys
                    visually messes up the edit line
           Product: konsole
           Version: 16.08.1
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: history
          Assignee: konsole-devel at kde.org
          Reporter: kde at dhardy.name
  Target Milestone: ---

1. Enable history search on up/down arrow by adding this to .inputrc:
> "\e[A": history-search-backward
> "\e[B": history-search-forward
See here: https://wiki.archlinux.org/index.php/Bash#History_completion

2. Start a new konsole session, and enter a long command (one long enough to
wrap to the next line within the konsole), and run it

3. Enter the first few characters of the previous command and press the "up"
arrow. Readline should complete the command for you. This used to work
correctly, but in recent versions of Konsole, the result is visually messed up.
The command still works if you try running it (despite looking garbled), but
editing it is tricky. There is some mismatch between what letters konsole
thinks is on the edit line and what is displayed.
