I'm mildly against this - we're not fixing an issue that's been found with some
specific compiler, the meaning of both versions is the same and
-Wmissing-field-initializers isn't in -Wall.  It feels like a warning that was
added for people following some overly prescriptive coding standard, not a
warning that's actually useful.

[Also, I'm surprised this is sufficient to squelch the warning given the
description of -Wmissing-field-initializers in gcc(1):

   Warn if a structure's initializer has some fields missing.  For example,
   the following code would cause such a warning, because "x.h" is implicitly
   zero:

       struct s { int f, g, h; };
       struct s x = { 3, 4 };
]
