+ Solve crash when passing "indir(`foo')" to "m4 -tfoo".
+ * src/symtab.c (lookup_symbol) <SYMBOL_DELETE, SYMBOL_POPDEF>:
+ Preserve placeholder when macro is being traced.
+ * src/builtin.c (m4_ifdef, m4_indir): A traced but undefined
+ symbol is not defined.
+ (set_trace): Remove placeholder when no longer traced.
+ (m4_traceon): On named traces, always reserve a slot in the
+ symbol table.
+ (m4_traceoff): Don't warn about untracing a nonexistent symbol.
+ * NEWS: Document new trace behavior.
+ * doc/m4.texinfo (Trace): Tracing by name now consistently works
+ no matter whether that macro is currently defined.
+ (Incompatibilities): Document differences between traditional and
+ GNU trace.
