There are cases where there is a useless space after ( and before )

if ( something ) {
}

Let's clean those up by removing the spaces.

This can be done with an awk script:

  {
        open_paren = gensub(/\([ ]*/, "(", "g", $0)
        close_paren = gensub(/[ ]*\)/, "\\1)", "g", open_paren)

        if (close_paren ~ "^)") {
                # Problem is the line is of type [ ]+)<other things>
                # Do some replacement to get it to replace subsequent " )".
                remove_first_spaces = gensub(/ )/, "#MARKER#)", 1, open_paren)
                remaining = gensub(/[ ]*\)/, "\\1)", "g", remove_first_spaces)
                close_paren = gensub(/#MARKER#/, " ", 1, remaining)
        }

        exclamation = gensub(/\![ ]*/, "!", "g", close_paren)
        print exclamation
  }
