[Gs-code-review] A fix for #517474 "Problem with hyphen in PDF using Minion"

[Igor V. Melichev]

[Log message beg]
Fix: Another improvement for the hack in 'getfontmetrics', which deals with
encodings where the same character appears more than once.
TeX-1.0a creates Differences with multiple appearances of 'hyphen'
character,
some of which specify zero width.
