- when the text parameter is constant col_add_str() and col_set_str() are equivalent but col_set_str() is faster. - same for replace col_append_fstr and col_append_str - remove col_clear() when it's redundant: + before a col_set/col_add if the dissector can't throw an exception. - replace col_append() after a col_clear() with faster col_add... or col_set https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=9344 svn path=/trunk/; revision=52948
