agreed.

IIRC e.g (! foo) has been the agreed style. Unfortunately uncrustify also
replaces '!!' with '! ! ' and there is no option to suspend this. This
would be super-easy to post-process but then we could not use the checking
option of uncrustify -- one option is to 'ignore' that in config, then
uncrustify won't change...

There perhaps is an uncrustify option for this. I cannot remember for that
either (perhame email/irc logs would tell something...)  I would have
guessed that no space there but ...

Again, would have guessed that char *foo is the syntax but...

We do have quite a few things where we cannot configure uncrustify to 
indent like emacs does: one is:

    variable = function_call
        (arg1, arg2)

which will indent:

    variable = function_call
                   (arg1, arg2)

or, if    

    use_indent_continue_only_once  = true

is set

    variable = function_call
               (arg1, arg2)


(getting all above figured out took like 100 minutes, by checking
Uncrustify-0.68_f options and some trial/error runs...)

before going to sleep (and interrupting diffing *.c w/ corresponding
*.uncrustify files...) we could change all above cases to

    variable = function_call(
        arg1, arg2)

then (IIRC, too tired to re-check) should indent like emacs(1) does...
