Error message misleading when protect file contains @

[moberghammer]

If a protect file is empty ( not containing a \r ) the following error is given:
failed to parse /zfs/cleaner_plans/cleaner_data_plan.conf: protected snapshot name include path

[abrander]

I'm unable to reproduce. I tried the following:

abrander@abk-desktop:~/src/github.com/cego/zfs-cleaner$ cat > test.conf
plan test {
	path a
	protect <p
}
abrander@abk-desktop:~/src/github.com/cego/zfs-cleaner$ touch p
abrander@abk-desktop:~/src/github.com/cego/zfs-cleaner$ ./zfs-cleaner test.conf 
abrander@abk-desktop:~/src/github.com/cego/zfs-cleaner$ 

How can this we reproduced?
