Documentation

Target length for lines in Backtrace buffers.

Backtrace mode will attempt to abbreviate printing of backtrace frames by setting print-level and print-length to make them shorter than this, but success is not guaranteed. If set to nil or zero, backtrace mode will not abbreviate the forms it prints.

This variable was added, or its default value changed, in Emacs 27.1.
