I meant to chime in the first time I saw this, but this isn't necessarily  
true.  I converted a bzr repo a few weeks ago, and it carried over not  
only trailing spaces, but LF in the middle of the tag name.  That made the  
.hgtags file... entertaining.  That can be fixed, but there might be such  
labels in the wild.
