That's what the "-" does in "<<-". It strips leading input tab chars
at the content and the last line, and was specified as such since the
first POSIX release in 1994:

  If the redirection symbol is <<−, all leading tab characters will
  be stripped from input lines and the line containing the trailing
  delimiter.
