Perhaps a preliminary clean-up patch is called for in such a case?

I do not think anybody can immediately see what the difference
between the old -1 and the new 0 in TESTSUITE_INIT macro means in
Dscho's alternative, but if we had a preliminary clean-up whose sole
change is to use designated initializers, the real "to-the-point"
step would become much easier to see which member that used to be
initialized to -1 is now getting zero-initialized.

And yes, changing the initializer style *and* the values the members
are initialized to in a same patch is much worse than sticking to
the style of the unreadable original.  It buries the real change in
the noise.
