New description:

 We currently give the advice to double quote the password for the Tor
 controller in the start-tor-browser script which seems to be a good thing
 given the trouble with quoting correctly. But this does not work (I wonder
 if it actually ever worked). The problem is that Tor Launcher is expecting
 a `HEXDIGIT` password. Using `deadbeef` is fine but
 {{{
 password[i] = parseInt(aHexPassword.substr(i * 2, 2), 16);
 }}}
 does not like things like `test` or {{{'"test"'}}} and is e.g. reporting
 for the former `NaN, NaN` which breaks the hashed control password option
 (the argument `aHexPassword` is spoiling the bug hunt a bit but I was not
 affected by it :) ). That in turn breaks the authentication and Tor
 Browser won't start.
