ARGS must be a plist, whose keys are `format' control strings and

string is allowed. The result will be concatenated into a single
string.
In the simplest case, it behaves as a sort of interleaved `format':
==========
\(orb-format \"A: %s\" 'hello
\" B: %s\" 'world
\" C: %s\" \"!\")
=> 'A: hello B: world C: !'
If format object is nil, it will be formatted as empty string:
==========
\(orb-format \"A: %s\" 'hello
\" B: %s\" nil
\" C: %s\" \"!\")
=> 'A: hello C: !'
Object can also be a cons cell. If its car is nil then its cdr
will be treated as default value and formatted as \"%s\":
==========
\(orb-format \"A: %s\" 'hello
\" B: %s\" '(nil . dworl)
\" C: %s\" \"!\")
=> 'A: hellodworl C: !'
Finally, if the control string is nil, the object will be formatted as \"%s\":
==========
