Isn't that what ert-batch-backtrace-right-margin is for ?
(defcustom ert-batch-backtrace-right-margin 70
"Maximum length of lines in ERT backtraces in batch mode.
Use nil for no limit (caution: backtrace lines can be very long)."
:type '(choice (const :tag "No truncation" nil) integer))
Also the TEST_BACKTRACE_LINE_LENGTH environment variable can be
used to set it (see test/Makefile.in).
