Bulletproof the debugger.

Don't ask me why but on my setup vsnprintf returned a value greater than
the size of the buffer (much bigger), resulting in the debugger tripping
a segment violation.
Considering the location of this code I see no problem with using belts and
braces; it isn't going to be executed much but when it is we want it to work
(despite braindead operating systems)
