Equals sign seems unnecessarily escaped

In rubygems, we sometimes print quite complicated commands when building extensions fail, so that the user can try to rerun things and reproduce the problem. I noticed that equal signs are escaped, making things a bit more overwhelming.

I think there might be a reason for it that I don't know of, or some shell where it's necessary, but I checked the equivalent python package, and it does not escape them, so maybe it can be changed.

➜  ~ python -c 'import shlex; print(shlex.join(["FOO=BAR", "baz"]))'
FOO=BAR baz

➜  ~ ruby -rshellwords -e 'puts Shellwords.join(["FOO=BAR", "bar"])'
FOO\=BAR baz

If the change is accepted, I can work on it.

Issue に示されている Shellwords.join のエントリポイントから開始し、等号を含むコマンドワードがどのようにエスケープされるかを追跡してください。出力を Python の例に一致させられるか判断する前に、既存のシェル安全性の動作を確認し、その後、他のエスケープケースを退行させることなく、等号が意図どおりに処理されることを検証してください。
