 Can't believe that we are still where we were more than two years ago...
 I think that we have to make this change even if it _might_ break some existing
 - current behavior is contrary to any documentation
 - current behavior is contrary to common sense
 - current behavior is very hard to describe and account for
 - I presume that very few people actually fully understand the current behavior
 - I presume that even fewer people made a conscious choice to depend or make use
 of its non-trivial features of the current behavior
 So, we should make the behavior of devfs pattern consistent with the
 documentation and the common sense.
 In addition to Jaakko's patch I propose that we pass FNM_PATHNAME to fnmatch(9),
 so that the matching is indeed consistent with glob(3) / shell glob-ing rules
 for filesystem paths.
