[Haskell-cafe] Excessive whitespace with tasty all of a sudden

I recently have been refactoring chatter, and finally got the test suite semi-operational (after lots of extensive changes, both to the library and to the tests to add tests and to make them compatible with the new APIs). Somewhere during the changes, the whitespace output by tasty to format the test status lines nicely has grown out of hand. For example, tests that used to show the OK message on the same line, now look like this (see below). Has anyone else run across this? Does anyone have debugging suggestions? Thanks!
