IMVHO, the systems on which this bug hits are far from common.  Remember
dtksh is not chosen by configure on any of these systems.  Further, we
have an easy workaround now (if only to separate variable names from
plain text, you could insert "`:`").  And we have seen to it that no
plain Autoconf code exposes this bug.  I see no convincing reason to
make the shell selection (which is in a hot path for everyone) slower if
we can otherwise live fine with this shell (and the user can still
work around this bug with CONFIG_SHELL).

I admit to not having tested though.  :)
