It was already inconsistent.  In grep et al a dot refers to a single
character, an * repeats the preceding character 0 or more times.
The shell uses ? for a single character and * means 0 or more of any
character at that position...  In any case there are several areas where
the shell differs from good ol' grep type RE's.  And as Maarten notes, it
IS consistent within itself.
