REPL: moving to beginning of line broken after selecting previous history item

[matthias314]

Enter a multi-line command on the REPL. Press Enter and then Ctrl-Up to get the input back, with the cursor being at the very end of input. Now press Ctrl-A. Instead of moving to the beginning of the last line of the multi-line input, the cursor moves to the beginning of the first line. This happens for all Julia versions from (at least) 1.10 to master.

I've figured out that somehow the code path

julia/stdlib/REPL/src/LineEdit.jl

Lines 2428 to 2429 in 215059f

	if s.key_repeats > 0
	move_input_start(s)

is triggered in the function move_line_start although Ctrl-A is only pressed once.
