The = command has recently been changed to use standard debugger serialization rather than to invoke a customizable function, or print_r otherwise. In the process a bug crept in that made the output not colored. This fixes that bug. It also updates the help text to make it clearer that = truncates text. While looking at that I noticed that the help text for the print command suggested that it's output is formatted with print_r. Fixed the text as well, but while I was at it introduced the "print r" flag to make it possible to invoke print_r, analogously to the already existing "print v" command. While adding test cases, I noticed that the truncation logic appears to be broken, so I fixed that as well. Differential Revision: D931565
