Yes, though the line that runs exec8.sub is actually in execscript, and
exec6.sub doesn't matter at all.  Changing ./ to ${PWD}/ should fix it.

This is strange, since the presence or absence or a controlling terminal
doesn't have anything to do with whether or not there's a cd in a startup
script that's not run by a non-interactive shell (that is, since the read
script isn't run by an interactive shell, your .bashrc isn't run).  Very
strange.
