Some terminals (xterm) supports two different 'character sets' ('G0' and
'G1'), which can be switched with 'SI' (shift in, '\017') and 'SO'
(shift out, '\016'). Each character set can be configured separately
and can be chosen from a list of pre-defined sets like 'ASCII Set' and
'Special Graphics'.
Running `TERM=xterm tput sgr0` to reset the terminal returns an escape
sequence starting with 'ESC ( 0', which selects the 'ASCII Set' for
'G0'. This currently is not understood by the Jenkins AnsiColor plugin.
Filter out those sequences, as they otherwise clutter the output.
