Print.c : fixes problem with line height in print_tanks

Browse source 
A "\n" was giving 2 lines height for the layout.
Wipping it out makes unnecesary the *2 divisor.
As there may be wrapped strings in tank we need to take
account of this height. There is no need, really, to get the
height of the gasmix or gas_consumed strings, as they are
"semi-fixed" size, but under some locales and imperial units they
could be wrapped too.
