[abcde] Bug#147726: abcde: not sh-compatible despite shebang line

[Ben Finney <bignose@zip.com.au>]

Package: abcde
Version: 2.0.3-1
Severity: normal

The shebang line that starts the abcde script:

=====
#!/bin/sh
=====

claims that the script can be executed under Bourne-compatible shells.
However, there are "bashisms" throughout the script, primarily the
bash-style command interpolation operators, '$(' and ')'.  For the
script to be Bourne sh-compatible, these would need to be backquotes '`'
instead.

I haven't investigated for other structures that invalidate abcde's
claim of sh-ness, but it seems likely that they could exist.

Since the current style of the script is preferable -- sh-style
backquotes are ugly and prone to error -- I think the best resolution is
to change the shebang line to specify the bash shell:

=====
#!/bin/bash
=====
