This "feature" is restricted at present to a few pairs of variables that are
hardwired at compile time.  They include:

CDPATH		cdpath
FPATH		fpath
MAILPATH	mailpath
MANPATH		manpath
PATH		path

These are documented in `man zshparam` and in the info files.  The remark
in the FAQ refers to the desire to provide arbitrary user-defined pairs
of variables that behave this way.

You might also wish to look into `typeset -U` which causes an array to
remove all non-unique elements from itself.  A function to test whether
any given directory is already in your path shouldn't be necessary.
