I built my ruby like so:
brew install readline
rvm install ruby-1.9.2-head -C --with-readline-dir=/usr/local/Cellar/readline/6.2.1/
When I do tab completion it appends a space after everything. I found in the docs that there's a variable called completion_append_character
. It's set to a space. If I set it to nil or any other character it still appends a space. How do I get it to stop appending a space after a completion?
