It seemed that this was needed for OS/2, in which \v(cmdfile) and other
file-oriented variables or functions can return filenames containing
backslashes, which are subsequently interpreted as quotes rather than
directory separators (e.g. see commented section for VN_CMDF below).
But the problem can't be cured at this level. Example:
type \v(cmdfile)
Without doubling, the filename is parsed correctly, but then when passed
to UNIX 'cat' through the shell, the backslash is removed, and then cat
can't open the file. With doubling, the filename is not parsed correctly
and the TYPE command fails immediately with a "file not found" error.
*/

nested -- e.g. functions whose arguments are functions, or recursive

function depth. Left for a future release...
