According to "The Open Group Base Specifications Issue 6" [1]:

${parameter#word}
    Remove Smallest Prefix Pattern. The word shall be expanded to
produce a pattern. The parameter expansion shall then result in
parameter, with the smallest portion of the prefix matched by the
pattern deleted.

We do require a POSIX-compliant version of sh already, right?
