Fixes #34724 - Fix hammer shell with pipe as stdin (#360)
Hammer shell tries to store terminal properties with stty -g and restore
them once it is done. This works rather poorly when the input is not a
tty (a pipe). When run in such a way, hammer complains about a couple of
things, depending on platform, possibly caused by different stty
versions.
This should prevent the following errors from showing up:
stty: 'standard input': Inappropriate ioctl for device
stty: invalid argument ‘’
Try 'stty --help' for more information.
