No.

Line continuation markers allow for such formatting without
reading the whitespace into the buffer.

       Leading  whitespace on continued regular expression condi­
       tion lines  is  usually  ignored  (so  that  they  can  be
       indented),  but  not on continued condition lines that are
       evaluated according to the sh(1) substitution rules inside
       double quotes.
