# Install working version
brew uninstall weechat; brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/4bdc1ce82824246dfa49d002033e1d6b2fcabe81/Formula/weechat.rb --with-python@2 --with-perl --with-ruby --with-lua --with-aspell

# Download perl script via weechat (make sure you type /quit in weechat to continue)
rm ~/.weechat/perl/multiline.pl ~/.weechat/perl/autoload/multiline.pl 2> /dev/null; weechat -r "/script install multiline.pl"; ls ~/.weechat/perl/multiline.pl 2>&1 > /dev/null && echo "It worked" || echo "It failed"

# Install broken version
brew uninstall weechat; brew install weechat

# Download perl script via weechat (make sure you type /quit in weechat to continue)
rm ~/.weechat/perl/multiline.pl ~/.weechat/perl/autoload/multiline.pl 2> /dev/null; weechat -r "/script install multiline.pl"; ls ~/.weechat/perl/multiline.pl 2>&1 > /dev/null && echo "It worked" || echo "It failed"

# If you ran line 5 and it said "It worked" and line 11 said "It failed", then you have reproduced the issue.

Note: You can pick any of the scripts from /script and this will fail. I just picked multiline because it was the one I was trying to install when I encountered the issue.
