Comment 2 for bug 1219107

Thanks for the patch: pretty amazing what non-"portable"
extensions are routinely permitted, this code has been
fed to splint and coverity and a fair number of compilers zillions of times.

The patch isn't quite right, an else is needed.

No easy fix for "ts=4" editing: I use "ts=8" with 4 space indents
(which is the default output from indent -kr and originally
dates back to Erik Troan's coding style in vi.
