Title: Add a configuration parameter to truncate long branch names.

Do you have any coding conventions for long lines? Because I definitely have a long one. Not sure if there is a more clear way to express that change.

Also, not sure about the deleted '<' line in airline.txt -- what does it do?

Works for me with the variable present or absent as expected.
