Bug#914494: sysvinit-utils: pidof behavior changed with omit option -o

[Alex Andreotti]

Package: sysvinit-utils
Version: 2.92~beta-1
Severity: normal

Dear Maintainer,

  * What led up to the situation?

I'm using a script that when start kills all the script with the same name but itself,
the syntax was:

pidof -o $$ -x script.sh

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

I did an apt upgrade today that installed sysvinit-utils_2.92~beta-1_amd64, my older version
in /var/cache/apt/archives was sysvinit-utils_2.88dsf-59.11_amd64 (Oct 14), the behavior
change should be in between.

If I use a shell `sh script.sh` or `zsh script.sh` it works, but `./script.sh` directly doesn't,
my /bin/sh link to dash, I don't think is relevant...

As a work around I use a for loop and compare with $$.
