Oddity In stty

["David L. Craig" <dlc@radix.net>]

I can't figure this out.  Why does the first pipeline suceed but the second fails?
I'm running an up-to-date Sid.

dlc@muse:~$                 fold -w `stty -a | head -1 | awk '{print $7}' | tr -d ';'` < /dev/null
dlc@muse:~$ cat /dev/null | fold -w `stty -a | head -1 | awk '{print $7}' | tr -d ';'`
stty: standard input: Invalid argument
fold: option requires an argument -- w
Try `fold --help' for more information.
dlc@muse:~$ 

-- 

May the LORD God bless you exceedingly abundantly!
