My recommendation was wrong -- I left out a step.  Try this:

_TMP=${BDEP_SOURCE#?} # everything but the first character

The first expansion gets matches our "suffix", and the second removes that

Niftily, this works right (for your purposes) even if $_TMP ends up
containing glob characters.  They'll be treated literally, and not screw up
your pattern.  To stuff a glob pattern to be used as such inside a variable
for use in a later parameter expansion would probably require a clever eval

Sorry for leading you astray with my first response.
