Subject: tools/shman.sh: Remove quotes in parameter expansions

POSIX doesn't list quote removal as one of the expansions to which
`word` (in `${parameter#word}` etc.) shall be subjected, but it does
mention quoting characters.  GNU Bash supports all three quote
characters.  Almquist shells support backslash, but not single or double
quotes.
