The first sed expression is missing "//".  Correcting that:

Yeah, I noticed the missing // in the first regexp, but only
after I had posted the message.  You're right, of course :)

It seems odd that the fixed expression doesn't work though.
Which version of FreeBSD is this and what sed are you running?

        $ uname -v

FreeBSD 4.11-STABLE #0: Wed Mar 22 19:18:33 MST 2006

        $ type sed

That's a sh-ism (normally I use csh):

sed is /usr/bin/sed

Interestingly, the problem is different on 6.1 (csh or sh):

sed -i -e 's/^[[:space:]]*//' -e 's/[[:space:]]*$//' test.txt
sed: -e: No such file or directory

...which is solved by giving a blank argument for -i:

sed -i'' -e 's/^[[:space:]]*//' -e 's/[[:space:]]*$//' test.txt

Gah.
