bug#16381: 24.3.50; align issue

[djcb]

When trying this with a simple c-program, it seems the `align' function
has changed behavior since 24.3; it no longer (by default at least)
gives at least one space, and in some cases actually breaks the code by
concatenating the type and variable name. E.g. write some like this
(after emacs -Q test.c)

int foo (int bar)
{
  char flub;
 
}

now mark the 'char flub' line, M-x align and we get:

int foo (int bar)
{
  charflub;
 
}

which gcc doesn't really appreciate. In general it seems that align does
not insert at least one space between type and variable in c-mode.
