Using archive-mode or tar-mode to visit archives touches
directory modification dates. This is especially annoying
when archives are located in backup directories. The problem
is in the function `insert' that temporarily modifies the
archive summary buffer causing lock-file to create a lock file
in the current directory that modifies the directory timestamp.
A similar bug#2295 was fixed by let-binding `buffer-file-truename'
to nil to prevent directory time modification in `lock_file'.
This is not a regression, so I propose to install in 24.2 something like
