Something I just realized, how should it behave with ed/sed/grep utilities? For
example should \A in their case end up meaning start-of-file (and
start-of-selection for sed when addresses are used), or should it end up being
equivalent to start-of-line, or be undefined-behavior (like start of the read
buffer would be)?

Thinking as a user I think \A being start-of-file would be interesting for
grep(1), but as an implementer, I could see it being rather annoying to support.
