0.21.0

New features and improvements:

• Column range for line is too long warning now starts at the first
  character beyond the length limit instead of the very first character
  of the line (#117).
• Error messages for invalid inline options are now a bit better, including
  reason why an inline option invocation is invalid and what is the name
  of the option at fault.
• ngx_lua std now contains full API definition for lua-nginx-module 0.10.10,
  so that operations on unknown fields within ngx global
  are now reported (#118).

Fixes:

• luacheck no longer aborts on internal error while checking files
  in parallel.
