NB: --config-file is troublesome, because get_defaults_options() doesn't
39
know about it, but we pretend --config-file is like --defaults-file. In
40
fact they behave differently: see the comments at the top of
41
mysys/default.c for how --defaults-file should behave.
43
This --config-file option behaves as:
44
- If it has a directory name part (absolute or relative), then only this
45
file is read; no error is given if the file doesn't exist
46
- If the file has no directory name part, the standard locations are
47
searched for a file of this name (and standard filename extensions are
48
added if the file has no extension)
