# Description: Tar 1.24 changed the ordering of name matching and
|
|
# name transformation so that the former saw already transformed
|
|
# file names (see commit 9c194c99 and exclude06.at). This reverted
|
|
# ordering made it impossible to match file names in certain cases.
|
|
# In particular, the testcase below would not extract anything.
