bug#12267: 24.2; sh-indent-comment bad default

[Leo]

--------------------------------
#!/bin/bash

function x() {
  #
    abc='a'
}
--------------------------------

Put the snippet in a sh-mode buffer and try indenting the comment line
(line 4). The default prohibits indenting any comment lines which
contradicts behaviour in all other modes. Thus I propose changing the
default value of sh-indent-comment to t to be consistent with other
modes.

I no one objects I will make the change in next days.
