OK, so that is really a problem with the eqnarray* environment.
In TeX, the interline space seems to be larger for this particular
environment. I fixed this for the next version.

Well, my point is not that mundane; it occurs for all kinds of
inline formulas which descend or ascend a bit too much.
Think about inline fractions, to give another example.

This is another instance of the same problem.

Thanks for reporting these details. Don't hestitate to contact about
typographic issues. The aim of TeXmacs is to provide a better
typesetting quality than TeX.
