It probably doesn't make sense semantically either, to put a '*' in
there.  Perhaps there should be an easy way to enter a multi-letter
variable?  It could be a macro that expands to each letter separated by
zero width space, and then anything that wants to read the TeXmacs
document for semantic content can be taught to see the argument of that
macro as a multi-letter variable name rather than as it's expanded
result.

For the 'd' in 'dx', I like to use the upright math-d you get by pushing
Tab a few times after typing the 'd'.  I type a "*" (invisible) between
the 'd' and the 'x' for the slight amount of space and since I think it
sort of makes sense, semantically.
