It doesn't. I've pasted a short program listing below to test with.
The patch I submitted will make delphi-mode indent the definition of
TestInterface correctly, except that *everything* between the first
instance of "interface" and "implementation" is indented one tab space
too far to the right.
The solution will be to have delphi-mode identify "interface", on its
own, as a unit section, and "= interface" as the start of an interface
definition. My patch makes the function "delphi-composite-type-start"
identify "= interface" as a composite type, so that's part of it done.
However, this seems to get overridden in delphi-enclosing-indent-of: As
I understand it, as the function parses the line it first identifies "=
interface" as a composite type and sets the indentation properly, but
then later parses "interface" again on its own and cancels the
indentation. (My patch makes the function ignore "interface" the second
time so the indentation never gets cancelled, but then that triggers the
problem illustrated by the code sample below.)
The fix may be as simple as making delphi-enclosing-indent-of interpret
"interface" as a unit section only if an equals sign wasn't previously
parsed, especially as there already seems to be some logic to do this
(see how the "equals-encountered" variable is used). But my LISPmanship
is poor and I couldn't get this to work myself.
I'll take another stab at it this weekend, but if someone monitoring
this list has experience with programming modes and is looking for an
easy enhancement to make, this could be it...

{ Sample unit for testing emacs bug #259, "delphi-mode does not

Result := 'Test Function Output';
