Bumps diff from 8.0.2 to 8.0.3.

Changelog

Sourced from diff's changelog.

8.0.3

  • #631 - fix support for using an Intl.Segmenter with diffWords. This has been almost completely broken since the feature was added in v6.0.0, since it would outright crash on any text that featured two consecutive newlines between a pair of words (a very common case).
  • #635 - small tweaks to tokenization behaviour of diffWords when used without an Intl.Segmenter. Specifically, the soft hyphen (U+00AD) is no longer considered to be a word break, and the multiplication and division signs (× and ÷) are now treated as punctuation instead of as letters / word characters.
  • #641 - the format of file headers in createPatch etc. patches can now be customised somewhat. It now takes a headerOptions option that can be used to disable the file headers entirely, or omit the Index: line and/or the underline. In particular, this was motivated by a request to make jsdiff patches compatible with react-diff-view, which they now are if produced with headerOptions: FILE_HEADERS_ONLY.
  • #647 and #649 - fix denial-of-service vulnerabilities in parsePatch whereby adversarial input could cause a memory-leaking infinite loop, typically crashing the calling process. Also fixed ReDOS vulnerabilities whereby adversarially-crafted patch headers could take cubic time to parse. Now, parsePatch should reliably take linear time. (Handling of headers that include the line break characters \r, \u2028, or \u2029 in non-trailing positions is also now more reasonable as side effect of the fix.)
