Actually, all these look pretty much as I'd expect:

By putting a comma there you've passed two parameters to the 'c'
function.  While the shell docs don't seem to mention it, a quick glance
at the source shows that there is indeed a c/2 where the second
parameter is the compilation options.  So you're trying to compile a
module called 'fm2' with an option of 2 (which probably doesn't mean
anything, but the missing file is the first problem that is picked up).

Here, you've put a full stop/period in the middle of an expression
(prior to closing the parentheses).  That's the character the ends
expressions, so of course it makes it illegal.

And here, by correctly wrapping the whole term in single quotes to make
it an atom, the syntax becomes correct.  The compile module seems to be
a little more permissive here than the docs suggest, allowing you to add
'.erl' to the module name and have it still work.

If by 'something with the shell' you mean 'the shell doing exactly what
it should', then yeah, I'd say there is indeed 'something with the shell' ;)
