Unless I misunderstand the question I think you could do it with
sed. I haven't tried though.

Thinking about it I see I am probably wrong in general but right for
certain setups. For example, the process will vary according to how
indents are implemented. Tabs or spaces? Does the display indent 
each line to same point as the preceding line or must each line be
separately indented?

The lines all run together problem is solved by replacing each ';' 
by ";\n" and fixing up the places where this goes wring. That's a
simple "replace all" in any editor.

   Correct me if I'm wrong, but  it needs something more than search &
replace if you've  got no indentation of blocks. You'll  need at least
regex  because it's  impossible  to say  if something  is  in a  block
without conditions.

   Search & replace could be good to change the indentation style, but
it can't say if those lines:

  |if(condition) {
  |    char foo[] = "bar";
  |    int  lenght = strlen(foo);
  |    int  i;
  |    for(i=0; i<length; i++) {
->|    instruction;
->|    instruction;
->|}
  |}

are inside a block.

   By the way,  why someone would format their code  in only one line?

I personally love indent. I will run 'indent -kr -nut' and the file name for 
kandr style indentation. And the -nut switch removes all tabs. I tend to tab 
alot.

Perhaps you can configure your editor to insert spaces when you type
<tab>.

In vim, you can do this by adding

    set expandtab

to your .vimrc.

(I'm not expressing an opinion about whether spaces or tabs are better.)
