So, we could do either of:
1. As Filipp suggests, just change the contract for
`ert-batch-backtrace-line-length' to: if set to nil, you
get
full stack traces, period.
2. change `cl-print-to-string-with-limit' to respect the
existing values of `print-length' & `print-level' when
`limit' is nil. Note that the only caller (in Emacs) of
this
function is the backtrace package.
I vote for option 2. What say you all?
I think the right way is 1 (which I already installed) because
then, as
the result of your patch, we get the ability to override
backtrace-line-length with ert-batch-backtrace-line-length,
and
nothing
more.
Changing the semantics of backtrace-line-length should be done
(if done)
in a separate issue, IMO.
Personally, I like that LIMIT in cl-print-to-string-with-limit
is "hard
override".
