The fix is probably the wrong way to solve the problem. It seems to work
ok but I am not sure it is ideal.

I have been trying to rewrite the file using some cc-mode extension
template. It is not that easy (CC-mode is not that trivial).

Syntactically as far as indentation is concerned E seems closer to
Javascript than C, C++ or Java. So I have had a look around about
Javascript emacs mode. From the writer of one of the javascript mode:

(http://www.emacswiki.org/cgi-bin/wiki/JavaScriptMode)

"I think however that Karl’s module has a better approach in that it is
not derived from another mode the way mine is. I took the easy (lazy)
route and derived mine from java-mode, seeing that the two languages had
a lot of keywords in common, and similar C-style syntax. While this
facilitated the syntax highlighting, comments, and the like, it also
produced some odd behavior in indentation and colorizing, owing to the
differences in the languages."

(PS java-mode is derived from CC-mode)

I have copied/paste (shame on me) karl's module and adapted a little
bit. It looks promising so far. I am wondering if it is not a better
starting point to get a better emacs mode.

I would love to have some feedback from the original authors of the
custom-e-mode. I don't know if it is possible to use the c-indent-line
function outside of the CC-mode (it seems it was the intention).

I would appreciate any comment from emacs E users out there ...

Please be aware that my current knowledge of both elisp and E is quite
limited.

PS Scala emacs mode does not use CC-mode either
