"dot" doesn't search path

["Mark H. Wilkinson" <mhw@mft.co.uk>]

the rc paper says

. [-i] file ...
     file. $* is set for the duration to the reminder of the argument
list following file. $path is used to search for file. Option -i
indicates interactive input ­ a prompt (found in $prompt) is printed
before each command is read.

the Unix man page says

     . [-i] file [arg ...]
          Reads file as input to rc and  executes  its  contents.
          With a -i flag, input is interactive.  Thus from within
          a shell script,

               . -i /dev/tty

          does the ``right'' thing.

note that $path isn't searched in the Unix rc. is this just an
oversight? I'd certainly find it useful if it did search $path. ".
/usr/local/bin/rcoraenv" is a bit of a handful.
