Frames don't have straight edges.

When I look at individual frames on negatives from some cameras, they
don't have straight edges. They have one or two tabs on the side.
What's that all about?

One could ask the same question of your description. One or two tabs,
eh? That's it?

Do they stick out? In? Are they cutouts near the sprocket holes or
along the actual film edge, are they dark areas, are they part of the
image frame or joined to it, how big are they, are these full frame
images, and... what camera/s did they come from...?

Are there so many different reasons for frames not to have straight edges
that all of that information is necessary?

They're part of the image, sticking out to the side, short enough that
they don't run into the next frame, longer along the edge than they are
sticking out, full frame images, on one side of the frame but not the
other, repeated on every frame in a roll, some have one tab and some have
two, and I don't know what cameras they come from.

Small 'V' cutouts mean a Hasselblad. Apparently Victor
wanted everyone to know when a picture was made with one of
his cameras. They are on all the 120/220/70mm backs, I
don't know about the Hassy panorama 35mm camera.

The are sometimes added with PhotoShop when that 'arty'
full frame 120 fashion shot is needed but the photo
was made with a digital camera.

If you are referring to the image on the film, this could be the
explanation:

On my Koni Omega Rapid M film holders, there is a series of holes along the
edge of the image frame. There is also a sliding mechanism that allows me to
cover some of the holes. On each of my film holders I have a different
number of holes uncovered. When the film is exposed, there will be a row of
dots exposed along one edge of the frame. If there is a problem with a
particular roll, I can look at the dots and determine which film holder was
used.

Also, on my nameless 2 1/4 square Ukranian copy of a Hasselblad, I have
filed notches in the edge of the image frame of each film holder; a
different number of notches in each holder. If there is a problem with film
advance (which does happen in this particular brand), I can determine which
holder needs to be trashed.

If you are referring to notches cut into the short edge of sheet films, the
shape and placement of the notches tells what kind of film it is. Also, the
notches allow you to determine which side is the emulsion side when loading
the sheet film. Depending on how you load, you will want the notches in a
particular corner.

The X-Pan does have a cutout too. While the V series 'Blads have two V
shaped notches 1cm apart, the X-Pan has a single notch, with a rounded shape
to it.

I have a 6x6 back that I can put on my monorail and field cameras - in my
more mischievous moments I've sometimes been tempted to file a couple of
notches into one edge of the film gate...

Speaking of notches, what about the holes punched into the leading edge of
some film strips? Looks like a code of some sort.

So they're likely... decorative?

I wondered whether they gave some kind of information to photofinishing
equipment, or assisted in frame edge detection or something.

I'd thought that all it would take is a convention and some software to
put additional information on 35mm film, like alerting the equipment to a
panoramic shot. But as far as I know, unlike with APS, the operator just
has to be alert to long, skinny frames on 35mm and handle them.

No, ego gratification for Victor: it identifies which
pictures were made with Hasselblad cameras.

Something like this?
