I don't know what these are. Are they non-Cygwin applications that are 
looking at the environment variable 'PS1'? Cygwin apps (e.g. 'printf') 
should cope with escapes correctly even in Windows consoles (otherwise 
even bash would not work).

Windows consoles don't understand escapes, period. Also AFAIK nothing 
except readline understands \[ and \]. But Cygwin understands escapes so 
Cygwin applications should work even in a Windows console.

Don't use escapes in non-Cygwin programs.
