[PATCH 02/10] diff: emit_{add, del, context}_line to increase {pre,post}image line count

[Stefan Beller <stefanbeller@xxxxxxxxx>]

From: Stefan Beller <sbeller@xxxxxxxxxx>

At all call sites of emit_{add, del, context}_line we increment the line
count, so move it into the respective functions to make the code at the
calling site a bit clearer.
