[PATCH 0/4] Don't warn about missing EOL for symlinks

"No newline at end of file" always confuses me when looking at a diff for
symlinks. "File? Huh? Didn't Git recognize my symlink?"

This mini series refactors the diff/xdiff code slightly to have the two
occurences of the warning both in diff.c, introduces a whitespace flag
WS_NO_EOL_AT_EOF to make this warning configurable, and actually changes
the default behaviour to what is described thorougly along with the
rationale in 3/4.

4/4 is a RFC - do we need to tweak this from config like other whitespace
warnings? 4/4 is lacking the Doc change for now.

Michael J Gruber (4):
  diff/xdiff: refactor EOF-EOL detection
  diff: make treatment of missing EOL at EOF configurable
  diff: Do not warn about missing EOL at EOF for symlinks
  RFC: add whitespace rule for no-eol-at-eof
