(extfs_read_archive): Likewise. Remove unneeded test.
Fix http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=286990
* extfs/ulha.in (mc_lha_fs_list): Use $NF instead of $10 as filename
for permission intention.

# Code for mc_lha_fs_run() suggested by:

# Jan 97 Zdenek Kabelac <kabi@informatics.muni.cz>
|
|
|
|
# Tested with mc 3.5.18 and gawk 3.0.0 on Linux 2.0.0

# Tested with lha v1.01 and lharc v1.02

# Nota bene:
|
|
# There are several compression utilities which produce *.lha files.
|
|
# LHArc and LHa in exist several versions, and their listing output varies.
|
|
# Another variable is the architecture on which the compressed file was made.
|
|
# This program attempts to sort out the variables known to me, but it is likely
|
|
# to display an empty panel if it encounters a mystery.
|
|
# In that case it will be useful to execute this file from the command line:
|
|
# ./lha list Mystery.lha
|
|
# to examine the output directly on the console. The output string must be
|
|
# precisely in the format described in the README in this directory.
