Here's a test I've just done, to get rid of \magnification oddities, 
with TL2004 setup in i-Installer: take story.tex (from 
/usr/local/teTeX/share/texmf.tetex/tex/plain/base/story.tex), copy it 
to a writable location and add

	\mag=\magstep1

at the beginning.

Then process it with TeX + dvips + GhostScript: the line breaks are not 
changed, the text is magnified by 1.2 but the page dimensions are 
unchanged, so that the text is cut on the right (it falls beyond the 
right page limit).

Process the same with pdfTeX: both the text and the page dimensions are 
magnified by 1.2.

I've done this both in TeXShop (with TeX + GhostScript mode on one 
hand, and pdfTeX mode on the other hand), and from the command line:

- using "tex story.tex" and TeXniscope to visualize the .dvi output;

- using "pdftex story.tex" and Adobe Reader to visualize the .pdf 
output.

Thus I don't think any dvips configuration file could play a role here.

Am I missing something obvious? Is the above normal behaviour, that I 
am erroneously interpreting as a bug?
