  Because that's what lappend does: it takes a list of *multiple* arguments,
and appends them as list elements to a variable.  By adding those gratuitous
quotes, you've turned the lappend command from multiple args into a single arg
with embedded spaces; you're thinking of shell scripting, but this is TCL.
