Another respondent corrected me -- $(foo) is a POSIX-ism, not a
bash-ism.  Debian policy says that /bin/sh can point to any
POSIX-compatible shell.

Relevant Debian policy quote:

=====
11.4. Scripts
-------------
     [...]

     The standard shell interpreter `/bin/sh' can be a symbolic link to
     any POSIX compatible shell, if `echo -n' does not generate a
     newline.[1] Thus, shell scripts specifying `/bin/sh' as interpreter
     should only use POSIX features.
=====

Since the $(foo) construct doesn't violate POSIX /bin/sh compatibility,
and I'm not aware of any other non-POSIX constructs in abcde, this bug
should be closed.
