Bug#16859 involves truncating column data at NUL characters. Instead, the

Browse Source 
client will now substitute spaces for NULs, so that the grid isn't messed up
due to silently consumed NULs and that the full field is shown.


client/mysql.cc:
  For non-numbers, print each character at a time, instead of using the 
  fprintf() facility, which interprets an array of chars as a C string, which 
  is necessarily NUL terminated.  We mustn't terminate on NULs, and since we 
  know the length of the data, we needn't.
mysql-test/r/mysql.result:
  Add a test.
mysql-test/t/mysql.test:
  Add a test.
