Not necessarily. The regexp may come from somewhere else (there was the Emacs manual about search-whitespace-regexp, though this is no longer the case, but this could be in various other places) and the user may test it without looking at the details, but he doesn't know that the behavior depends on the major mode, so that his tests are actually wrong. -- Vincent Lefèvre - Web: 100% accessible validated (X)HTML - Blog: Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
