Sorry guys, but this turns out to be wrong. POSIX has an additional
paragraph which I skipped earlier:
: When pattern matching is used where shell quote removal is not performed
: (such as in the argument to the find -name primary when find is being
: called using one of the exec functions as defined in the System
: Interfaces volume of IEEE Std 1003.1-200x, or in the pattern argument
: to the fnmatch( ) function), special characters can be escaped to remove
: their special meaning by preceding them with a backslash character. This
: escaping back slash is discarded. The sequence "\\" represents one literal
: backslash. All of the requirements and effects of quoting on ordinary,
: shell special, and special pattern characters shall apply to escaping
: in this context.
This clearly says that backslashes must be interpreted.
