Hm, yes, I was thinking in terms of typing commit messages for VC, or
editing Gnus Parameters, etc.  I never found those to be inconvenient.
The problem with the one-character proposal is that is not easy to
test -- the display engine isn't there yet.

I'd like to have a good test case first.  Do you have one?

I thought it trough with "my CAR123" but didn't see the problem.
(Except for the known problem of what to consider to be "reasonable",
hehe.)

Here's a little textual description of what we would like to see.
Assume the following visual presentation, with point shown as !:

my CAR123! is cheap

And here's the logical representation, with point is therefore at
either of the two positions shown as !:

my 123!RAC! is cheap

It doesn't matter where point is, however.  If point was between 3 and
R, no action is needed, because the buffer now contains:

my 1234!RAC is cheap

If point was between 3 and SPC, then the buffer now contains:

my 123RAC4! is cheap

No action is needed because it still transforms into the required
visual representation.

Alex.
