Vim regex examples

In a diff, search for added lines containing 'bacon', and highlight only 'bacon'

/^+[^+].*\zsbacon

; Explanation:
; /           <- start search
; ^+          <- has a + at the beginning of the line
; [^+]        <- does not have another + after that (avoid +++-lines)
; .*          <- match anything up until...
; \zs         <- start highlighted area (match)
; bacon       <- what we're actually looking for
