[minor] nim doc renders generic badly (extra `;`): `template default[T; ](t: typedesc[T]): T` + bad formatting

[timotheecour]

• extra ;
  nim doc test.nim

template default*[T](t: typedesc[T]): T =
  ## returns default value for type ``T``, and can work at compile time
  defaultImpl[T]()

#renders as:
template default[T; ](t: typedesc[T]): T
#instead of:
template default[T](t: typedesc[T]): T

• bad formatting:

proc test1*[T](x: T) : T =
  ## A test function v2
  runnableExamples:
    doAssert test1(12) == 12
  return x

shows as:

doAssert test2(12) ==
    12

instead of

doAssert test1(12) == 12
