[BUG] 'find' doesn't combine '-exec ... {} +' with parentheses

[Martijn Dekker]

BusyBox 'find' cannot combine '-exec ... {} +' with parenthesis 
arguments. This should work.

A simple test case:

$ find /dev/null \( -exec printf '%s\n' {} + \)
$ find /dev/null \( -exec printf '%s\n' {} \; \)
/dev/null

The first command prints nothing with Busybox 'find'; it should print 
/dev/null like the second.

Thanks,
