Good catch, I forget to check examples in docs.

-T largefile would have to be quoted:
tst_mkfs ext4 /dev/device "-T largefile"

But then you'd have to always pass a device ($TST_DEVICE).
And the problem is that I wanted to specify the options before loading
tst_test.sh (together with TST_FORMAT_DEVICE=1). At this point TST_DEVICE
is empty string. Therefore I'd prefer to quote fs-options to be passed to
tst_mkfs as single option.

OTOH mostly only fs-size is the parameter, not really used now.

Kind regards,
Petr
