"""
Lists old versions of a corrected message.
Usage
-----
.. glossary::
/display_corrections
**Usage:** ``/display_corrections [number]``
This command lists the old versions of a message.
Without argument, it will list the last corrected message if there
is any. If you give an integer as an argument, ``/display_corrections``
will go back gradually in the buffer to find the message matching
that number (starting from 1, for the last corrected message).
If you are scrolling in the buffer, Poezio will list the corrected messages
starting from the first you can see. (although there are some problems with
multiline messages).
