Done. I'll finish to play with svn latter.

Thanks ^^

That's something I miss too. I'm not sure there is a workaround. We can
always play with recorded macros, or quick'n'dirty mappings.

'if' is what is expanded within comment/string context.

Def_AbbrC() does some other things like:
- adding \n before (,{ and after ),} according to options.
- removing markers/placeholder according to another option.

It forces to reindent the line where the cursor is, it works in
INSERT-mode.
I see I have hard-coded <c-f>. It is not the best solution as I should
have used what is defined after the `!' in 'cinkeys'.

Indeed.
Surround() has also another responsibility. I wrote it before vim7
permit to distinguish between visual-mode mappings and select-mode
mappings. Surround() checks if the current selection is a
marker/placeholder. If so, it expands 'if' in insert-mode (which will
result in the activation of the previous `if' abbreviation), otherwise
it does its surrounding work.
It also accepts some other options regarding reindentation, ...

Otherwise, your analysis of my examples are correct.

May be, you can look into InsertIfNotAfter() that I define at the end
of ftplugin/cpp/cpp_set.vim (check the newly uploaded lh-cpp.tar.gz
tarball archive). I use it to define the abbreviation for `namespace'
and the mapping on <m-t>.
What you will need is to analyze the lines before the cursor. if the
`if' you are typing starts a new instruction, then you can expand
`if (!cursorhere!) {\n!mark!\n}!mark!', otherwise just
`if (!cursorhere!);!mark!'.
checking for the previous non comment code can be a little tricky.

Feel free to ask for any precision.
