pgindent messing up "translator: " comments

I just noticed that this comment got reindented by pgindent
(xlog.c, line 3226 in REL9_1_STABLE):    /*     * translator: First %s represents a recovery.conf parameter name like
 * "recovery_end_command", and the 2nd is the value of that parameter.     */    ereport((signaled && failOnSignal) ?
FATAL: WARNING,            (errmsg("%s \"%s\": return code %d", commandName,                    command, rc)));
 

Sure enough, the resulting POT entry does not have the necessary
comment:

#: /pgsql/source/REL9_1_STABLE/src/backend/access/transam/xlog.c:3230
#, c-format
msgid "%s \"%s\": return code %d"
msgstr ""

I think the proper fix would be to use the /*---- trick, such as in
postmaster.c:
    /*------      translator: %s is a noun phrase describing a child process, such as      "server process" */
 (errmsg("%s (PID %d) exited with exit code %d",                    procname, pid, WEXITSTATUS(exitstatus))));
 

It seems to me that we should alert if pgindent does anything to a
comment line containing "translator:".
