The syntax of the script suggests the Bourne-shell. If this is the case one
can tell the Shell to ignore the space in the name, i.e. do not treat it as
name separator.

The IFS parameter tells the Bourne-shell which characters use to separate names
(IFS means: internal field separators), so before the "for j in $trashlist"
line, one can insert the declaration :
IFS="
"
(i.e. IFS string, equal sign, double quote, return, and double quote again)
This will tell the Shell to take all names from the trashlist up to the
new line sign.

The manual for sh(1) informs, that IFS is ignored for root, and when the
effective user is different from the real one. I have checked for root and
it still works.
Manual bug ?  :-)
