perhaps the above "In case" sentence should read:

  In case of comma-separated multi-body headers, $(hdr(name)[*]) returns
  all the bodies, comma-separated.

while testing this, i found a bug.  when incoming request has

Test: <sip:user1 at foo.bar>.
Test: <sip:user2 at foo.bar>,<sip:user3 at foo.bar>.

xlog("L_INFO", "Test '$(hdr(test)[*])'\n");

produces:

Apr 25 17:11:37 siika /usr/sbin/sip-proxy[9801]: INFO: Test '<sip:user1 at foo.bar>, <sip:user2 at foo.bar>,<sip:user3 at foo.bar>'

the bug is the extra space char after first comma.
