Yes, but please mention "--eval", and add an index entry so that this
text would be easier to locate.  Something like this:

  @cindex emacsclient, getting a backtrace
  @cindex backtrace from emacsclient's @option{--eval}

Also, a nit: I don't think we use "elisp" in the manual, we say
"Lisp" instead.

Thanks.
