[bitbake-devel] [PATCH] fetcher: Fixed remote removal not throwing exception.

[Christopher Larson]

This will try to rm origin even if there's an 'originfoo' remote, as you
don't check for an exact match on a line, but a general substring search.
Unlikely, I admit, but we should still work as correctly as possible, I
think.
