Sorry, I don't remember the exact culprits, but they did exist, though
I haven't run into one for many years.

<http://unix.org/whitepapers/shdiffs.html> says:

     Some [older] systems have allowed the end of the word to
     terminate the backquoted command substitution, such as in:

       "`echo hello"


     This usage is undefined; the matching backquote is required

This exactly corresponds to the behavior described in the Autoconf manual.
