There is a difference between multi-line paste and single-line paste.
When you paste multiple lines into the command line window, it
immediately executes each line, one at a time, without displaying the
lines in the command line, and without you being able to modify the
command before it's executed. (NOTE: The last line of a multi-line
paste is also executed immediately.) However, with a single-line paste,
the command is left in the command line window, and not immediately
executed, so that you can modify it before executing it.

What you might be running into is the case where you have a single
statement, but you have also copied a newline character at the end of
the statement. When you paste this into the command line, it will
behave like a multi-line paste and immediately execute the (single)
command and not give you a chance to edit the command before execution.

The presence of a carriage return/newline character anywhere in the
pasted text determines the difference between multi-line and single-line
paste behavior.
