Let's say the lack of comments did not help me ;)
Copying it back again and adding comments; now 3.23->4.0
replication of LOAD DATA INFILE works again.
Since my changes, rpl_log.test, whose result file depends on file_id, became
non-repeatable, i.e. file_id on slave in SHOW BINLOG EVENTS
changed depending on the order of tests (sometimes 1, sometimes 5).
Which is logical: as now the slave does not copy Create_file and Exec_load from
the relay log (i.e from the master's binlog) to the slave's binlog, but
instead lets mysql_load() do the logging, the file_id is now the one whic
was used on the slave. Before it was the one which was used on the master,
and by chance the master was always restarted for this test because there's
a -master.opt file, so file_id on the master is always 1. But now file_id is
from the slave so we need to restart the slave. That's why I add an (empty)
-slave.opt file. I could have used 'server_stop/start slave', but this
would have required the manager, so most of the time mysql-test-run silently
skip the test which makes it useless. And I want this test to be run !
"LOAD DATA INFILE is badly filtered by binlog-*-db rules".
There will probably be a second final one to merge Dmitri's changes
to rpl_log.result and mine.
2 new tests:
rpl_loaddata_rule_m : test of logging of LOAD DATA INFILE when the master has binlog-*-db rules,
rpl_loaddata_rule_s : test of logging of LOAD DATA INFILE when the slave has binlog-*-db rules and --log-slave-updates.

problems in master_pos_wait()...
Still this brokes some functionality in sql/repl_failsafe.cc
(but this file is not used now)
the first 4 bytes of the relay log. Indeed comments in mysys/mf_iocache.c
say we must always use my_b_append for such a cache.
This *could* avoid a very rare assertion failure which is:
030524 19:32:38 Slave SQL thread initialized, starting replication in log 'FIRST' at position 0, relay log '/
users/gbichot/4.1.1/mysql-test/var/log/slave-relay-bin.000001' position: 4
030524 19:32:38 next log '/users/gbichot/4.1.1/mysql-test/var/log/slave-relay-bin.000002' is currently active
mysqld: mf_iocache.c:701: _my_b_seq_read: Assertion `pos_in_file == info->end_of_file' failed.
and which seemed to happen always when the SQL thread and/or the I/O thread
were at position 4 in a relay log.
mysqlbinlog segfaults if --position is just before Exec_load event
mysqlbinlog prints uncommented warnings if --database and compiled with debug
mysqlbinlog --database does not filter LOAD DATA INFILE
