Change the display of hunks in hunk splitting mode to preserve the diff
heading, which hasn't been done ever since the hunk splitting was
initially added in v1.4.4.2-270-g835b2ae.
Splitting the first hunk of this patch will now result in:
Stage this hunk [y,n,q,a,d,/,j,J,g,s,e,?]? s
Split into 2 hunks.

This makes it easier to use the tool when you're splitting some giant
hunk and can't remember in which function you are anymore.
The diff is somewhat larger than I initially expected because in order
to display the headings in the same color scheme as the output from
git-diff(1) itself I had to split up the code that would previously
color diff output that previously consisted entirely of the fraginfo,
but now consists of the fraginfo and the diff heading (the latter of
which isn't colored).
