But it's not difficult to strip out initial indentation using pure Lua code:

For instance, pl.text.dedent:

--- dedent a multiline string by removing any initial indent.
-- useful when working with [[..]] strings.
-- @param s the string
-- @return a string with initial indent zero.
function dedent (s)
    local sl = split(s,'\n')
    local i1,i2 = sl[1]:find('^%s*')
    sl = sl:mapn('sub',i2+1)
    return sl:concat('\n')
end
