Details:

unpacking into /tmp produces the following:


unpack("http://mirrors.ctan.org/support/tex2rtf/rtfutils/rtftohtml/README.gz";,
"/tmp")


mv: `/tmp/oct-WqCcGr' and `/tmp/oct-WqCcGr' are the same file
error: unpack: unable to move files to "/tmp": 
error: called from:
error:   /usr/local/share/octave/3.7.7+/m/miscellaneous/unpack.m at line 207,
column 9

Corresponding errors occur with unpacking tar files. For example,


unpack("ftp://ftp.gnu.org/gnu/bc/bc-1.03.tar.gz";, "/tmp")


just produces a copy of bc-1.03.tar.gz in /tmp. In contrast,


unpack("ftp://ftp.gnu.org/gnu/bc/bc-1.03.tar.gz";, "/tmp/foo")


does extract into /tmp/foo.
