remove non printable characters from code (#470)
Non printable ESC character is required to obtain terminal escape
sequence i.e. for changing output color.
Such sequences (especially ESC character) were replaced by command
substitution producing exactly same result (variable value), but using
only "safe" characters.
Use of printf and especialy '\033' or '\0ddd' sequences is described
here:

Use of $(command) or command substitution is described here:
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/V3_chap02.html#tag_18_06_03
Verbatim TAB characters were replaced with \t escape sequence as
described to avoid problems with editors silently replacing them or
developer accidentialy messing up the regex.
