check-code: make repquote distinguish more characters for exact detection

This patch makes repquote() distinguish more characters below, as a
preparation for exact detection in subsequent patch.

  - "%"  as "%"
  - "\\" as "b"(ackslash)
  - "*"  as "A"(sterisk)
  - "+"  as "P"(lus)
  - "-"  as "M"(inus)

Characters other than "%" don't use itself as replacement, because
they are treated as special ones in regexp.
