SC2145 false positive when using backslash-newline

[krayon]

For bash, a line ending with a backslash causes a false positive unless the backslash is proceeded with a space, eg:

echo "${@}"\
    |less

The following script:

#!/bin/bash

echo "1: This should not cause SC2145 error but does"; echo "${@}"\
|less

echo "2: This should not cause SC2145 error but does"; echo "${@}"\
    |less

echo "5: This should not cause SC2145 error but does"; echo "${@}"\
    "test"

echo "3: This correctly does not cause SC2145 error"; echo "${@}"|less

echo "4: This correctly does not cause SC2145 error"; echo "${@}" \
    |less

echo "6: This correctly does not cause SC2145 error"; echo "${@}" \
    "test"

echo "7: This correctly causes a SC2145 error"; echo "${@} test"

Gives the following output:

In test.bash line 3:
echo "1: This should not cause SC2145 error but does"; echo "${@}"\
