Yup - COL_INFO should contain more than the minimum amount of
information about the packet; it should contain a useful one-line
summary of the packet's contents.

There is, but it requires a routine that's in the CVS tree,
but that may not be in the 0.7.7 release - "col_append_fstr()", which
lets you append a formatted string to the COL_INFO column.  (0.7.7 had,
I think, "col_append_str()", so you could "snprintf()" to a string
buffer and "col_append_str()" that, but "col_append_fstr()" is a bit
cleaner, and does less string copying.)

I've checked in a version of your change that uses "col_append_fstr()".
