[tex-live] Problem with 'mathtext' package after update of 'cyrillic' one

[Karl Berry]

Vladimir's test document:

    \documentclass{article}

    \usepackage{mathtext}
    \usepackage[T2A]{fontenc}
    \usepackage[utf8]{inputenc}
    [...]

works for me without change in the current (TL pretest) LaTeX2e. That is
a nice surprise :). I hope it is expected behavior. --thanks, karl.
