bug#25337: space after compile-command is a hack

[積丹尼 Dan Jacobson]

compile-command is a variable defined in ‘compile.el’.
Its value is "make -k "

You know that trailing space is a hack and shouldn't need to be inserted
by the user.

E.g., I did
(setq compile-command "make")
and now I regret it... I'm now going to have to use
(setq compile-command "make ")

I don't understand, the user *doesn't* need to insert it.  They can do
so if they wish...

What do you want to be different?

If one doesn't insert the space, then you have to add it each time,
else you will execute makea.out instead of make a.out.

So how do you want Emacs to behave differently?

At least in the compile-command docstring mention "be sure to add a
space at the end."

I feel like this is redundant.  "If you want a space at the end of the
string, don't remove the space from the end of the string."  It could
apply to any variable.

I suggest, "It is often useful to leave a space at the end of the
value."

Looks reasonable, I've pushed a patch with that addition to emacs-25.
