I think this is a documentation problem. Grep programs apply patterns to files
line by line, so \A does indeed anchor to the start of a line, not to the start
of the whole file. I think all grep programs behave this way for ^, and \A is
just a variant of that.

Because you have used the -M option, the actual matching string is permitted to
extend over several lines, with (in this case) the newlines being matched by
\s. I have made a note to try to improve the documentation.
