/*

|
* Convert a size_t value to int, by saturating it at INT_MAX. Useful
|
|
* if you want to use the printf idiom "%.*s", where the '*' precision
|
|
* specifier expects an int in the variadic argument list, but what
|
|
* you have is not an int but a size_t. This method of converting to
|
|
* int will at least do something _safe_ with overlong values, even if
|
|
* (due to the limitation of printf itself) the whole string still
|
|
* won't be printed.
