Log message:
        * src/macro.c (expand_macro): In macro expansion errors, report
        line number at open parenthesis.
        * src/input.c (next_token): Fix off-by-one bug in reporting end
        of file in unterminated comment and string.
        (file_names): New obstack, necessary since expand_macro now hangs
        on to file names longer than the files remain open.
        (input_init): Initialize new obstack.
        (push_file): Use new obstack.  Delay updates to current_file
        until after expand_macro has restored state.
        (peek_input, next_char_1): Update current_file if necessary.
        (pop_wrapup): Release memory.
        * doc/m4.texinfo (Macro Arguments, Changequote, Changecom): Catch
        the off-by-one bug.
        (Dnl): Update to the new location reporting rules.
        * NEWS: Document these changes.
