Note: RS may only contain a regex in gawk and mawk. In regular awk only the first character is used.

Although the -s (squeeze) option is said to work on the input set only, this seems to work:
Code:
tr -s ', ' '\n' < file

My choice would be sed, but the 'tr -s' solution is neat if you have it.
Code:
sed '
  s/, */\
/g
 ' in_file >out_file

Nice, it needs a small adaptation for it to work on all systems (for example HP-UX, AIX):
Code:
tr -s ', ' '[\n*]' < file

or
Code:
tr -s ', ' '\n\n' < file

-s does not only work on the input set:
Quote:
When the -s option is specified, after any deletions or translations have taken place, repeated sequences of the same character shall be replaced by one occurrence of the same character
