Sadly I did try this. It didn't work. The text was not transformed as
expected. I think it might be because the colour escapes are not
straight forward text. This is why I ended up, after wrestling with sed
for a while trying to tweak the regexp, going with ssed. It could
handle the escapes.

Anyway, thank for suggesting it as it made me look more closely at bash
string manipulations and arrays. But I think I will leave the script as
it stands, dependant on ssed.
