Unclear how to do multiple transformations in one invocation

[pierreganty]

Hi there,

In the fsm man page I read:

 -t name
           Apply a transformation. Multiple transformations may be given, and are applied in the order given. 

However, if I provide two transformations (as, for instance, -t trim minimise) it returns an error. Moreover, looking at https://github.com/katef/libfsm/blob/2483417ec80bf62f45ddd9d864405677917d06cd/src/fsm/main.c#L256 I do not see how it would support multiple transformations.
