find contrib -name CVS -o -name 'Makefile*'
find contrib '(' -name CVS -o -name 'Makefile*' ')'

Теперь уже и сам не понимаю. :(
Наткнулся на проблему c -print0.
[at@ungrund elinks-0.4.0]$ find contrib -name CVS -o -name 'Makefile*' -print0
contrib/Makefilecontrib/Makefile.amcontrib/Makefile.in[at@ungrund elinks-0.4.0]$
[at@ungrund elinks-0.4.0]$ find contrib '(' -name CVS -o -name 'Makefile*' ')' -print0

Это выражение эквивалентно
$ find contrib -name CVS -o '(' -name 'Makefile*' -print0 ')'
> [at@ungrund elinks-0.4.0]$ find contrib '(' -name CVS -o -name 'Makefile*' ')' -print0

Если все ещё непонятно, напишите мне лично, я расскажу. :)
