Fix early wrapping of the command line when using git-prompt.sh

From: Richard Quadling <[email protected]>

When running git-prompt in Bash, the lack of \001 and \002 causes the command line to wrap early.

The issue is the current \001 and \002 were not themselves escaped and so resulted in binary 0b1 and 0b10 being present, rather than the strings "\001" and "\002".
