Subject: [PATCH] pattern matching for namedev

As promised yesterday, here is a patch to implement a more advanced
pattern matching instead of the simple '*'.

We can remove the "tty"="tty" line from udev.rules now and
replace "tty*" by "tty[0-9]*" to catch only the vc's.


  implement pattern matching in namedev
  '*'  - to match zero or more chars
  '?'  - to match exactly one char
  '[]' - character classes with ranges '[0-9]'and negation [!A]
