bug#16015: 24.3.50; newline indents in shell script mode

[Jarek Czekalski]

Steps to reproduce:
emacs -Q
C-x C-f test.sh
type "if [[ 1 ]]; then"
M-x newline

Expected behaviour: a new line indented with left margin (column 0).
Found: a new line is indented by four spaces, as if newline-and-indent
command was executed.

I checked "newline" documentation and found no explanation for that.
