read -n is confused by \

[Brett Kail]

Hello,

Description:
    If the nth character of read -n is a \, then bash reads one too
many characters.

Repeat-By:
    echo 'abc\abc' | (read -n 4; echo $REPLY)

Additionally, the documentation for 'read' is unclear what happens for
\ when -r is not specified in that it does not distinguish between
"maximum number of characters read" and "maximum number of characters
read into the variable".
