[bsdtextproc] week #2 status

[Ben Fiedler]

(I have started the project a week late since I was on vacation, as noted in
my timeline)

work on *diff*:
I've starting by adding a few couple features which are available in GNU
diff.  I'm still familiarizing myself with how everything in diffreg.c works
together (some of the functions are poorly commented, but gdb is helping me
determine the context), which is essential knowledge for most of the
required changes.  I will likely need to modify my milestones to allocate
more time working on diff.
