Completed items not guaranteed to sort to the bottom of list

[pafoster]

The README states:

These two goals are why, for example, lines start with priority and/or dates, so that they are easily sorted by priority or time, and completed items are marked with an x, which both sorts to the bottom of an alphabetical list and looks like a filled-in checkbox.

To ensure that completed items sort to the bottom of list, it is sufficient that item descriptions start with an upper-case ASCII character (as is the case for many of the examples provided, though not all). Here is a counter-example:

xylophone lesson
x Find ticket prices

The 'xylophone lesson' is an example given in the README, more generally a user might encounter the same issue if item descriptions are written in lower-case ASCII / unicode in a non-English lanuage.

The README should clarify that completed items are not guaranteed to sort to the bottom of the list, if the item description does not start with an upper-case ASCII character. Alternative non-breaking fixes are:

• Require that descriptions start with an upper-case ASCII character
• Make the creation date non-optional
• Make the priority non-optional
