Well, they work with *my* grep 2.5.1. grep has had bugs, but a bug as
enormous as $ not working would have failed most of grep's own testsuite
and never have been released.

(Well, OK, that depends upon locale to some degree, but unless you're
using Basque or something it'd probably have still been spotted.)

What does `od -a' say about the line endings? are they `cr lf' or just
`lf'?

'Cos I just checked, and grep does indeed not autoconvert DOS files for
you unless you're actually running under DOS, and this has exactly the
symptoms you're seeing. (See the description of the effect of the
`--binary' option in the grep info page.)
