This particular curl command returns a JSON message that does not end with
a newline. Bash (readline) starts reading the next command with the
physical cursor at column 1, which it has no way of knowing. Readline
assumes the cursor starts at column 0 when it computes where the cursor
needs to be for redisplay. You can hit newline or use ^L to redraw the
line and make sure it starts in column 0.
