variable namestr. New local variable error. Initialize macro_entry
members file, line, and name. Don't return when encountering an
error, just record the fact. Use %s in some diagnostics for read.c
to insert the macro name. Free macro_entry on error.
(macro_expand): Pass macro_entry to macro_epand_body. Don't return
when encountering an error, just record the fact.

the fact.

Adjust mis-spelled diagnostic. Use is_name_beginner.
* read.c (try_macro): New.
(read_a_source_file): New static variable last_eol. Don't list
macro expansion lines more than once. Call try_macro.
