62856465f2 In the printf() library, measure width and precision in characters rather 
than bytes if the "!" (alternate-form-2) flag is present on a %s or %z
substitution.

fa385edff3 A new approach to very large sqlite3_mprintf() strings: Back out the 
[d655a665] check-in and instead make the size fields in StrAccum unsigned.
Strings generated by sqlite3_mprintf() can now be as large as 2^31-1 bytes.
