Works as documented:
`${PARAMETER#WORD}'
`${PARAMETER##WORD}'
The WORD is expanded to produce a pattern just as in filename
expansion (*note Filename Expansion::). If the pattern matches
the beginning of the expanded value of PARAMETER, then the result
of the expansion is the expanded value of PARAMETER with the
shortest matching pattern (the `#' case) or the longest matching
pattern (the `##' case) deleted. If PARAMETER is `@' or `*', the
^^^^^^^^^^^^^^^^^^^^^^^^^^
pattern removal operation is applied to each positional parameter
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
in turn, and the expansion is the resultant list.
