Bash Version: 4.3
Patch Level: 42
Release Status: release

Description:
When using a here document in combination with newline escapes the
command is incorrectly recorded in the history

Repeat-By:

This command works correctly:

$ cat << END && cat \
/dev/null
hello!
END

Press "up" and it is replaced by this:

$ cat << END && cat /dev/nullhello!
END

Resulting in this error
cat: /dev/nullhello!: No such file or directory

Fix:

Needs to retain the newline between /dev/null and hello! which is
erased for some reason.
