[Bug-barcode] [PATCH] Text width issues

[Ryan]

When using code128 in particular, several letters overlap.  Most 
prominently, upper-case M and W, but also others.  They are very wide 
and not being given the extra room they need.  e.g.  barcode -e code128 
-b MWMW0M00W01

I can increase the margin, but that doesn't look very good and wastes a 
lot of space all the time, just to catch the few worst-cases.  My simple 
fix is to undo to the change to Helevtica (see ChangeLog), which has 
variable width characters, and go back to fixed-width CourierBold.  It 
works nicely here.
