[pdftex] Correct use of font expansion.

[John Culleton]

I use plain pdftex. Here is my current setup:
----------------------------------------------
\pretolerance 200
\tolerance 400
...
\font\rm putr8r at 10pt
...
\rm
\input protcode.tex
\pdfprotrudechars=2
\setprotcode\font
\pdffontexpand\rm 20 20 5 autoexpand
--------------------------------------------

Is this code correct and sufficient?  It does not yield an error message but I 
still have problems with a few overflow lines in my text, in particular a 
long word at the end of the first line of a paragraph thus:
-------------------------------------------------------------
\par ``Consider me a representative of God on earth. Remember the
Twenty-third (etc)
--------------------------------------------------------------
The word fragment "Twenty" overflows the line. I can hyphenate it to Twen\-ty 
but this puts an additional hyphen in a word already hyphenated.  

If my micrographic expansion code is functioning then I can take other means 
to eliminate the error, such as inserting \break after "Remember the", or 
negative kerning between words etc. .  But I want to make sure that 
micrographic expansion and contraction is correctly configured first.
