branches/5.1:

Fix formatting of the autoinc-lock-mode command line parameter.

Old view (./mysqld --help --verbose):

  --innodb-autoinc-lock-mode=#
                      The AUTOINC lock modes supported by InnoDB:
  0 => Old
                      style AUTOINC locking (for backward compatibility)
  1 =>
                      New style AUTOINC locking
  2 => No AUTOINC locking
                      (unsafe for SBR)

New view:

  --innodb-autoinc-lock-mode=#
                      The AUTOINC lock modes supported by InnoDB:
                      0 => Old style AUTOINC locking (for backward
                      compatibility)
                      1 => New style AUTOINC locking
                      2 => No AUTOINC locking (unsafe for SBR)

Looks like these strings are "automatically" wrapped by MySQL in the
following way:
* newlines (\n) in the string are ignored
* newline separator (\n) is inserted every 57 or so characters.
* lots of white space is appended to each inserted new line.
