I'm trying to find all the files in this directory whose names are starting
with "ab", ending with "cd" and have between 4 and 5 digits between them. One
way to do this, would be the following regex:

   ab[0-9]{4,5}cd

So I tried:

[19:04:49 address@hidden:~/tmp/muell/finde] $ find . -regex
'./ab[0-9]{4,5}cd'
[19:04:54 address@hidden:~/tmp/muell/finde] $ find . -regex
'./ab[0-9]\{4,5\}cd'
[19:04:57 address@hidden:~/tmp/muell/finde] $

The find man page states, that "basic" re should be supported. If so, then
the RE is correct - testing it with grep shows, that it is indeed correct:

[19:08:12 address@hidden:~/tmp/muell/finde] $ find . | grep
'./ab[0-9]\{4,5\}cd'
./ab12345cd
./ab1234cd


Why are the bounds in the RE not honored?
