I have a fancy prompt with colors, and now bash doesn't seem to know how wide my terminal is. Lines wrap around incorrectly.
You must put \[ and \] around any non-printing escape sequences in your prompt. Thus:
BLUE=$(tput setaf 4) PURPLE=$(tput setaf 5) BLACK=$(tput setaf 0) PS1='\[$BLUE\]\h:\[$PURPLE\]\w\[$BLACK\]\$ '
Without the \[ \], bash will think the bytes which constitute the escape sequences for the color codes will actually take up space on the screen, so bash won't be able to know where the cursor actually is.
If you still have problems, e.g. when going through your command history with the Up/Down arrows, make sure you have the checkwinsize option set:
shopt -s checkwinsize;
Refer to the Wikipedia article for ANSI escape codes.
