Hi there,

it looks like tar integration is broken in Xfe as of OpenBSD 7.6. In 
OpenBSD 7.5 the user could use a contextual menu to compress and 
decompress files and folders, which would cause Xfe to invoke tar. Now, 
when issued a compression command, Xfe tries to call tar with the "a" 
option, which as far as I know is a gnucism, and causes the command to fail.

STEPS TO REPRODUCE:

Launch Xfe, navigate to some directory in which folders and file exist, 
use the right click conteXtual menu to attempt and compress some of them.

OUTCOME: A warning window pops up with a failure message:

tar: unknown option -- a
usage: tar {crtux}[014578beFfHhjLmNOoPpqsvwXZz]
            [blocking-factor | format | archive | replstr]
            [-C directory] [-I file] [file ...]
        tar {-crtux} [-014578eHhjLmNOoPpqvwXZz] [-b blocking-factor]
            [-C directory] [-F format] [-f archive] [-I file]
            [-s replstr] [file ...]
