This Atom package intends to provide simplistic syntax-highlighting in patch files generated by various version control softwares.
Honestly, this package is somewhat redundant. The language-diff package performs the same functions as this and uses the TextMate syntax definitions, so is likely more flexible overall. This is just a small toy of mine that happens to have some functional purpose.
Good catch. Let us know what about this package looks wrong to you, and we'll investigate right away.
