[suggestion] Option to display weekday

[AkashaRepo]

I have TTY-clock running on various TVs around my house and it is my primary way of telling the time of day when I'm not either outside (with my phone) or working at a desktop (when I use other clocks)

One feature TTY-clock lacks that my other clocks have, is that it does not tell me the day of the week, even though it displays the date. I have to consult a calendar if I want to know what day it is. It would be really nice if TTY-clock could have an option display a three letter day of the week abbreviation (MON TUE WEN THU FRI SAT SUN) to the left of the time, similar to how there is an option to display seconds on the right side.

One can display the weekday with a date format like:

-f "%A %m/%d/%Y"

I'm using the above, which displays the full day name. That exposes a bug in the date window size calculation method. The size is calculated when the program starts, but not recalculated when the length of the date string changes.
