find regular expression question

[Volodymyr Kostyrko]

   Just stumbled upon some inconsistences in find(1) regular expressions 
parsing:

[code]
 > :>a
 > find . -regex '^\./a\?$'
 > find . | grep '^\./a\?$'
./a
[/code]

   It seems that find just dumps away '?' operand. The same regexp 
perfectly works in grep.

   Is this a bug or feature? Am I missing something?
