[debian-mysql] Bug#830976: logrotate failures if mysql server is not running

Package: mariadb-server-10.0
Version: 10.0.27-2
Followup-For: Bug #830976

Actually, I think this might be bug in grep. If I run `my_print_defaults
--mysqld`, I get:

But grep doesn't match. When we slightly change the grep command, it
does work:
my_print_defaults --mysqld | grep -Po "pid-file=\K.+$"

`my_print_defaults --mysqld | grep -Po "pid-file=\K[^$]+"` does match,
and strangely, so does `echo '--pid-file=/var/run/mysqld/mysqld.pid' |
grep -Po "pid-file=\K[^$]+"`, or `my_print_defaults --mysqld | grep -Po
"pid-file=\K[a-z/]+"`, or `my_print_defaults --mysqld | fgrep pid-file |
grep -Po "pid-file=\K[^$]+"`.

`my_print_defaults --mysqld | grep -Po "pid-file=\K[^?]+"` for instance
fails. Anyway, I guess I should report this as a bug against grep, or is
there something I've missed?

Included is a patch to use `.+$` instead of `.[^$]+`, which should fix
this issue for mariadb.
