M4 version 1.4.3
When tracing it turned on, the expansion isn't always shown correctly.
Witness:
# m4 --interactive
define(`echo1', `$*')
define(`foo', `This is macro `foo'.')
echo1(foo)
This is macro This is macro foo..
traceon
echo1(foo)
m4trace: -2- foo
m4trace: -1- echo1
This is macro m4trace: -1- foo
This is macro foo..
The last expansion "This is macro foo.." should be "This is macro This is
macro foo..".
