#4658 tcl::prefix error message wrong

[Christian Nassau]

this error message is wrong:
% tcl::prefix match -message xxx
bad option "xxx": must be -message

it should be
wrong # args: should be "tcl::prefix match ?options? table string"

[Peter Spjuth]

The error message is actually correct. The call is correct.
You asked for the string "xxx" to be matched to the table
containing "-message", and there was no match.
The two last arguments are always the table and the string,
only if there are more, it is searched for options.
