>From pdftex.ch:

@!pdf_first_space_corr: integer; {amount of first word spacing while drawing a string;
for some reason it is not taken into account of the length of the string, so we
have to save it in order to adjust spacing when string drawing is finished}

when I pdftexed the example and examined the result in acroread4.05/linuxi386,
nothing seems odd to me, everything look ok. But when viewed by gv, there are
some unwanted space before the exclamation marks.

If I remmember correctly, "some reason" looks rather like a bug of acrobat
reader and pdf_first_space_corr was introduced as a workaround. But I am
not sure, I may have missed something in the pdf spec.

I don't have AR-5.* to check, and xpdf somehow doesn't work at all.
