4089	diffutils-3.6	bdubbs@…	lfs-book@…	"New minor version.

** New features

  When one file is a prefix of the other, cmp now appends the shorter file's size to the EOF diagnostic.

** Bug fixes

  Using an invalid regular expression with --ignore-matching-lines=RE (-I) no longer causes stack overflow.  Before, with an invocation like the following, diff would diagnose the error, but would still proceed to blow the stack: [[br]]
{{{
diff -Ia -I\\ <(echo) < (echo b) [bug introduced in 2.9]
}}}
  diff no longer mishandles line numbers exceeding 2**31 on Mingw-w64.

  the ---presume-output-tty (ostensibly test-only) option would cause diff --color to read an uninitialized variable [bug introduced in 3.4]

** Performance changes

  diff's default algorithm has been tweaked to deal better with larger files, reversing some of the changes made in diffutils-3.4.
