            Bug ID: 33835
           Summary: [clang-format] function arguments
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Formatter
          Assignee: unassignedclangbugs at nondot.org

clang-format is breaking lines without need:

Using the option AlignAfterOpenBracket: DontAlign, I configured clang-format to
start the list of new parameters (almost) at the beginning of a new line:

It seems that without need, clang-format moves the first parameter on the
second line, while it perfectly would fit into the first line:

# Original (in our isl math library)
__isl_give isl_ast_expr *isl_ast_expr_get_op_arg(__isl_keep isl_ast_expr *expr, 
        int pos)                                                                
        return 0;                                                               

# clang-format
__isl_give isl_ast_expr *isl_ast_expr_get_op_arg(                               
        __isl_keep isl_ast_expr *expr, int pos)                                 
        return 0;                                                               

I would prefer the first version. Is there a way to teach clang-format to
prefer the first version?
