The patch in attachment.

[andrew_b]

Can we get rid of isoinfo -d -i double run in test_iso()?

[asy]

It is possible but it complicate code. Need something like

ISOINFO_D_I=`isoinfo -d -i "$1"`

if [ "Joliet with UCS level 3 found" == "`echo $ISOINFO_D_I|sed "s/.*\(Joliet with UCS level 3 found\).*/\1/"`" ]; then
 echo 1
fi

On the other hand "isoinfo-d-i" is cached and works fast second and more time:

$ time isoinfo -d -i tc1000_doc_lib_v.4.3.iso | tail
0.00user 0.00system 0:00.00elapsed 400%CPU (0avgtext+0avgdata 2672maxresident)k
