/**
* nsPrintfCString lets you create a nsCString using a printf-style format
* string. For example:
*
* NS_WARNING(nsPrintfCString("Unexpected value: %f", 13.917).get());
*
* nsPrintfCString has a small built-in auto-buffer. For larger strings, it
* will allocate on the heap.
*
* See also nsCString::AppendPrintf().
