I thought about it when choosing the character. The save icon uses the
3.5″ floppy disk (when it depicts a floppy disk at all), so I took the
5.25″ one to avoid ambiguity.

Well, most other editors use either an asterisk or a bullet. I didn’t
feel like inventing a new symbol usage for its own sake.

What does clicking the * do now? Just drop the “buffer modified” flag?
That feels dangerous.

Well, DOS stands for Disk Operating System, so the DOS line end
convention gets a disk icon. Windows does not enter the picture
because it just inherited the DOS convention.

Nowadays, I think, floppy disks are not used, like, at all (except
possibly to file tax reports to the tax office, and even they now
provide a tax form web application), so the image of a floppy evokes
the thought of something ancient.


Point is, U:--- is a cryptic indicator that basically says “everything
is as you expect”, and 1\%*@ is a cryptic indicator that says “there
are so many things wrong, unusual or unsafe about this buffer”. These
are all important status items that could be made more informative
when in their abnormal, unsafe or attention-required state; or,
conversely, quieted down to silence when in the usual, safe and
expected state.
