was code added to detect or die on sighup recently?

[L. A. Walsh]

I have a script that normally runs my snapshot that I haven't
used for the past several days because something seemed
to be going wrong and I wanted to run things manually.

But running the script twice today, I got:
>  snaphome
Found 15 mounted dated, snaps or snap archives
»[snapper#2120]base_mp=/home
1 snap dated today.
  (Use: '--force=force_create_snap' to force another snap.)
  Checking other snaps for needed attention...
Oldest Snapshot = Home-2014.08.03-02.05.53.
Rsync with 9 excludes from config file...CODE(0x7f6098) at 
/home/perl/perl-5.16.3/lib/site/Carp.pm line 169.
rsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at 
rsync.c(632) [sender=3.1.1]
rsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at io.c(513) 
[Receiver=3.1.1]

But when I run the snapper script manually, I don't get such an error...

Odd...

The snaphome script is designed to run the snapper script (which calls 
rsync)
and send it's log to a file and allow it to be automatically monitored...
