mention there is no way to get rid of the space when Appending

[積丹尼 Dan Jacobson]

In (info "(make) Appending")

     Often it is useful to add more text to the value of a variable already
     defined.  You do this with a line containing '+=', like this:

          objects += another.o

     This takes the value of the variable 'objects', and adds the text
     'another.o' to it (preceded by a single space).


Mention:

*One might think that using e.g.,

          objects +=another.o

might get rid of that space, just in case it is not preferred in some
situations, but alas, there is no way to get rid of that space.
