Subject: [ruby-core:114064] [Ruby master Feature#19752] Allow `--backtrace-limit` to appear in RUBYOPT

Issue #19752 has been reported by tomstuart (Tom Stuart).



----------------------------------------

Feature #19752: Allow `--backtrace-limit` to appear in RUBYOPT

https://bugs.ruby-lang.org/issues/19752



* Author: tomstuart (Tom Stuart)

* Status: Open

* Priority: Normal

----------------------------------------

The `--backtrace-limit` option was added in #8661 but it is not currently supported in the `RUBYOPT` environment variable, which appears to be a mistake. Unlike other long options which are not allowed in `RUBYOPT` (e.g. `--copyright`, `--version`, `--dump` and `--help`) it does not cause the interpreter to terminate, and cannot cause harm if read from the environment. During the initial discussion about the `--backtrace-limit` feature, Matz [suggested](https://bugs.ruby-lang.org/issues/8661#note-27) that he expected `RUBYOPT` to allow this option.



Patch here, which also documents `--backtrace-limit` on Ruby���s `man` page: https://github.com/ruby/ruby/pull/8010
