It looks like a horrible mish-mash of legacy Bourne shell syntax,
edited later by another person using certain post-Bourne shell constructs
(note the inconsistent use of test and [ commands), with quoting failures
thrown in for good measure (lots of [ -e ${foo} ] commands).

I cringed at the `expr` all over the place, and stopped reading halfway
through.

The shebang is #!/bin/sh and it's using half-Bourne half-POSIX code, so
if you suspect a bug in bash, why not just let it run under some other
shell?  /bin/sh does not link to bash on most operating systems.  Not
even on all of the Linux-based operating systems.
