Changed to conform to POSIX.2, 4.24.4: the first argument that starts with

Browse Source 
a -, or is a ! or a (, and all subsequent arguments shall be interpreted
as an expression ...
The behavior before this change can cause a non-option (eg -owner instead
of -user) to be interpreted as a file name.  Depending on the expression
used, this could cause serious damage:

	find . -owner jtc -exec rm \{\} \;

Will delete every file.
