Write that changelog entry as:

	PR middle-end/50607
	* c-tree.h (c_expr_t): New typedef for struct c_expr.
	(C_EXPR_APPEND): New macro.
	* c-parser.c (c_parser_get_builtin_args): Preserve
	original_tree_code of c_expr structure.
	(c_parser_postfix_expression): Adjust to the new function.

(note top marker and without the "Fixes...")
and there'll be an automatic entry in bugzilla, like for example
PR50609.  You still have to close the bugzilla entry manually
(not all noteworthy fixes are reason to close a bug report).

Mostly as a note for the future but you could fix that now, when
adding the missing empty line after the date+email line. ;)
