You don't say in what way Mathematica is not plotting this function as
you expect to see it.

In Mathematica 4, I get a correct graph of the function -- although it
does not show me the part of the sloped line below y = 0.85.  (Recall
that Mathematica decides what part of the range is "appropriate".)

Try, say:

   Plot[t - (t - 1) UnitStep[t - 1], {t, 0, 5}, PlotRange -> All];

You will undoubtedly get what you "expected" to see.
