t9001: style modernisation phase #5jc/t9001-modernise

Two general shell script codingstyles around here-text.

 - Quote the <<\END_OF_HERE_TEXT string when there is no parameter
   substitution going on to reduce cognitive load of the reader.

 - Indent the text with <<-\END_OF_HERE_TEXT when able to make it
   easier to spot boundaries of the tests.
