Hello! Big thanks for sharing your .dot files and yours habr articles.
I'm using your .bashrc, but found, that under GNU Screen something wrong in prompt:
Wrong characters appear in the line first:

^[[4;1Ruser@testub1804s:~ ----------------------------------------------------------------------------------------------------------------------------------------------------------------
➜
^[[7;1Ruser@testub1804s:~ ----------------------------------------------------------------------------------------------------------------------------------------------------------------
➜
^[[10;1Ruser@testub1804s:~ ----------------------------------------------------------------------------------------------------------------------------------------------------------------
➜
^[[25;1Ruser@testub1804s:~ ----------------------------------------------------------------------------------------------------------------------------------------------------------------
➜ cd /var/backups/
^[[25;1Ruser@testub1804s:/var/backups -----------------------------------------------------------------------------------------------------------------------------------------------------

Please, help fix this.
