Trace shows second argument to AC_SUBST

[Peter Eisentraut]

I just tried out the new trace facility on Autoconf's own configure.in:

$ ./autoconf --trace=AC_SUBST configure.in

and got some lines like

configure.in:8:AC_SUBST:AUTOTEST_PATH:m4_default([..], [.])
configure.in:9:AC_SUBST:EXPR:$ac_cv_path_EXPR
configure.in:15:AC_SUBST:M4:$ac_cv_path_M4

Where are the second arguments coming from, and btw., why is the
m4_default call not expanded?
