Use an explicit hexadecimal constant for READ_BUF_SIZE, correct ChangeLog. src/ChangeLog addition: 2014-01-20 Aidan Kehoe <kehoea@parhasard.net> * fileio.c [...] (READ_BUF_SIZE): Use an explicit hexadecimal constant for the 0x20000 value for this, don't left-shift 2 16 times. Correct the last ChangeLog entry after Jerry James pointed out a mistake on my part. Thank you for review and discussion, Jerry and Stephen Turnbull.
