Thank you for the fix. This is much simpler => better as fix.
Unless anyone objects, I'll apply it on Wednesday.

Actually missing quotes caused that (i.e. working: "$*" or "$@", not working: $* or $@), I
got into common trap of different behavior with/without quotes as I tested only both variants
without quotes. Using "$@" instead of "$*" is IMHO better, as it's similar to new API in
tst_test.sh.

Either I miss something in the new API, or it'll need to be changed for new API anyway:

$ df01.sh -f ext2 -s "100 500 1000"
df01 1 TINFO: parse_args: 1:'s', 2:'100' (@:'s 100')
...

Tested with following patch:
---
diff --git testcases/commands/df/df01.sh testcases/commands/df/df01.sh
