On Linux and most other operating systems I know of, passing a NULL to

The case in the filed bug is fairly trivial to fix, but I'm wondering
if this is something that should be added to the Code Style /
Portability section of README.developer?
Alternatively, since I have no idea how many of these bugs we may have
to fix, perhaps we should be wrapping all format strings somehow?
Hopefully someone with some Solaris experience (or even a Solaris test
box) could weigh in, since I have neither.
For the record we last discussed this a little over a year ago:
http://www.wireshark.org/lists/wireshark-dev/201105/msg00202.html
As for adding something to the doc: sure but I doubt it'll help much.
I'm a fan of a macro like Jakub mentioned as part of the old conversation:
http://www.wireshark.org/lists/wireshark-dev/201105/msg00205.html
If we go that route, perhaps someone can add a bit to checkAPIs that
complains if it finds %s in a format string without the macro?
That might be a bit tough: we'd have to parse the text string counting
the % conversion specifiers and then find the corresponding argument and
check it for the macro.
