What happens is that running
ssh git@host perms reponame
appears to hang, since it is waiting for STDIN. I added a message to
help, since we don't want users losing files accidentally!
(The other alternative is to add a specific option for batch mode, but
this is backward incompatible for people who have scripts that may be
doing this).
thanks to Caleb Cushing for catching this
----
The "make sure Ctrl-C gets caught" thing needs some explanation.
Without it, a user could inadvertently lose his gl-perms file if he ran
the command in batch mode. You'd think that the Ctrl-C would hit the
for (<>) {
line and bail, but it manages to reach the
_print( $pf, @a );
line somehow. Even trapping SIG INT does not help.
I suspect it is to do with how signals are propagated by ssh across a
"no-pty" session, but am not sure.
