similar fix as escaping banner message

Just fast note. This is evaluated only in progressmeter, where it is
printed out not-escaped, but only control characters for terminal.

The issue can be fixed by this simple patch, quite similar way as the
banner is printed out. Patch may require some more handling of
allocated memory. But here is the basic idea.
