	Has anyone else had problems with using an internal
eqn construction with .IP in groff(V1.05)?

	In other words, I can't seem to do this:

.EQ
delim $$
.EN
[.... some groff stuff]
.IP $lambda$
[... more groff stuff]

I get error reports that look like:
sect4:51: warning: missing `)' (got `'')
sect4:51: warning: missing number
sect4:51: warning: numeric expression expected (got `\{')
sect4:51: warning: missing closing delimiter
sect4:51: warning: missing number
sect4:51: warning: `par*label' not defined
sect4:51: cannot chop empty macro
sect4:65: warning: indent cannot be negative

and of course no output.

	Since this is more or less "simple" stuff, I'm surprised
that groff chokes so easily.
