About reliability: Yes, it's poor. It just uses diff's
"-p/--show-c-function" option which is really hacky and simply prints
the last-seen line that looks like a function declaration before the
hunk it prints. It doesn't work properly for many situations including
added/deleted functions, and when the function declaration appears in
the context lines of the hunk, and when editing the doc string before a
function declaration. Both GNU diff's and svn diff's "-p" options are
like this.
