From: Jim Cromie <jim.cromie@gmail.com> In FT_comma_terminators, ddcmd "module params =_" was executed immediately before ddcmd "module,params,=_" 'kernel/params.c'. Because flags were already cleared (=_), the second command produced a zero-length diff, causing verify_after_change() to fail due to expected fingerprint drift. Prime params call-sites with +p prior to testing comma delimiters, ensuring a valid +p -> =_ state transition diff.
