align multiple regexp in one line

[Fabian Braennstroem]

Hi,

    I am trying to align lines with several characters, e.g.
    a comma separated list, with align-regexp.
    The line looks like:
    word1, word2 , word3, word5
    wordasdf1, wordasdlfk2 , wordasdlf3, word5

    Marking and using 'align-regexp ,' would just create the alignment 
according to the first comma.
    Is there a function, which aligns the whole region?

Greetings!
 Fabian
