#50 Fix for gerbv when there aren't enough digits

[Mitch Davis]

Hello,

A patch for gerbv. I was having trouble reading this file:

M71
M48
T12F00S00C5.200
%
T12
X009734Y00055
X002634
X011287Y008
X001081
M30

This file should be metric, and 4 digits, with leading zero suppression.
However, note that 00055 and 008 don't have enough digits. So gerbv reads
the values wrong. With this change, gerbv works ok.

If we're in 'omit trailing zeros' mode, and if a coordinate has less digits
than expected, then pad with implicit zeroes.

Useful patch! I hope it gets applied.

I think this is already fixed in git commit b0b55e7589e4dc626e77a0bcffd134c3b212fc81
