Use greek letters in the shell prompt

[sinewalker]

I very much like the lambda in eshell, instead of a dollar-sign:

~/Work/svn/puppet λ 

It would be nice to have something like this in bash too. Perhaps alpha or beta for normal and continuing prompts, and omega for root?

List of greek letters to select from: https://www.w3schools.com/charsets/ref_utf_greek.asp

or perhaps better: https://unicode-table.com/en/sets/greek-symbols/

Perhaps beta/alpha should be swapped? still to decide. very low priority, so this will probably be done quickly ;-)

for z-shell (if I ever use it, which is unlikely): ʓ

I think use β small letter beta for the primary prompt (because it evokes "bash", and also it still looks similar to traditional $)

For the secondary prompt, I think technically the greater-than should be replaced with one of these:

• ≻ Succeeds
• ⊱ Succeeds under relation
• ⪼ Double Succeeds

For all of them, only use the greek letters if the terminal's character encoding is UTF-8.

All of these work on a Linux UTF-8 terminal. I think the Succeeds / Succeeds under relation work better because they are heavier glyphs
