[pdftex] Changes to pdfTeX margin protruding?!

[Julian Gilbey]

[BTW, the README file - which may only be part of teTeX - still refers
to tug.cs.umb.edu, which I believe is no longer the case.]

Using pdfTeX 3.14159-1.00a-pretest-20011114-ojmw ....

So having created lots of nice Type1 EC fonts and tried using pdfTeX
with \protrudechars=2, I discovered that something's not right; my
hyphens were falling *way* out into the margins....

I've read through the code and found out why: Knuth's suggestion of
specifying the protrusion factors in terms of an em has been used in
place of Han's original specification, but as there doesn't even
appear to be a pdfTeX changelog anywhere, it was not easy to discover
this.

Any chance of doing some or all of the following?

(1) Creating a changelog and/or news file

(2) Reverting the change back (end of char_pw, around line 4800 in
    pdftex.ch, which says: round_xn_over_d(quad(f), c, 1000); rather
    than something to do with the char width

(3) Modifying protcode.tex to do something more intelligent

Especially as TUG has just published Han's thesis, I can't imagine
that I'm the only one to fall foul of this problem....

Thanks!

   Julian
