Details:

This is no bug-port but a request for discussion.

touch a0 b

now try to search for files with a name ending in a number (i.e. a0). With
4.2.2[123] you'll need to use
find . -regex '.*[0-9]\+'

with earlier versions you'll need
find . -regex '.*[0-9]+'

This breaks backwards compability but OTOH the new syntax (requiring \+)
matches GNU grep behavior.

Basic regex seem to be painful, glibc claims to support "POSIX regex
functions" but the basic regexes it actually implements match neither the
definition given in regex.7 (claiming to document POSIX 1003.2) nor the online
available IEEE Std 1003.1, 2004 Edition. (A implementaion of POSIX re e.g.
would not be allowed to support \|)
