GNU中的空格

Question

看这一段话，

Go's untyped constants mean that you can use a floating point number as
an array length, as long as it has an integral value.  That works fine,
but some of the tree code wound up using a floating point constant
unexpectedly, leading to a compiler crash.  This patch fixes the
problem.  Committed to gccgo branch.

注意，语句之间是两个空格。

看这段注释，

/* Return the tree node if an ARG corresponds to a string constant or zero
   if it doesn't.  If we return nonzero, set *PTR_OFFSET to the offset
   in bytes within the string that ARG is accessing.  The type of the
   offset will be `sizetype'.  */

注意，语句之间是两个空格。还要注意的是，结尾的注释，也是空了两个。

OMG，颠覆了我对从小学的英语的观念。
