Some commands (typically invovling gemsets) trigger sed errors

[ritchiea]

See below. It always triggers the sed error 6 times and will also happen if I execute rvm gemset list but will not happen if I run rvm use x.x.x without specifying a gemset.

$ rvm --debug use 2.1.2@ymstaging
sed: -e expression #1, char 11: unterminated address regex
