(I'm going through older Emacs bug reports that have received no
response.)
That seems a reasonable thing to add, and it's in patch form below. But
what makes me hesitate to add it is that there's a commented-out
"\\sqrt[3]" in the file... Does this mean that this should be
"\\sqrt[2]"? Why is it commented out in the first place? Don't
latin-ltx people like squares? And roots?
So if anybody else who uses this input method could weigh in here, that
would be nice.
