[dependabot]

Updates the requirements on prompt-toolkit to permit the latest version.

Changelog

Sourced from prompt-toolkit's changelog.

2.0.10: 2019-10-03

Bug fixes:

• Handle HANDLE sizes correctly on windows. This made things break randomly.on 64 bit systems.
• Handle terminal size correctly when reported as (0, 0).
• Fix width computation in progress bar formatter.
• Fix option-up and -down on Mac with iTerm2.
• Removed ctrl-c in confirmation prompt.

New features:

• Added PROMPT_TOOLKIT_NO_CPR=1 environment variable to disable CPR requests.
• Accept a pattern in WordCompleter.

2.0.9: 2019-02-19

Bug fixes:

• Fixed Application.run_system_command on Windows.
• Fixed bug in ANSI text formatting: correctly handle 256/true color sequences.
• Fixed bug in WordCompleter. Provide completions when there's a space before the cursor.

2.0.8: 2019-01-27

Bug fixes:

• Fixes the issue where changes made to the buffer in the accept handler were not reflected in the history.
• Fix in the application invalidate handler. This prevents a significat slow down in some applications after some time (especially if there is a refresh interval).
• Make print_container utility work if the input is not a pty.

New features:

• Underline non breaking spaces instead of rendering as '&'.
• Added mouse support for radio list.
• Support completion styles for READLINE_LIKE display method.
• Accept formatted text in the display text of completions.
• Added a FuzzyCompleter and FuzzyWordCompleter.
• Improved error handling in Application (avoid displaying a meaningless AssertionError in many cases).

2.0.7: 2018-10-30
