12488,read_string_while duplicates character,George <juergen.sawinski@…>,John Maddock,"Streaming, e.g. ""1W"" into a multiprecision number will correctly recognize 1, but the first character after the number will be duplicated (from ""1W"", ""WW"" is left in the stream).

The cause is the line

    is.rdbuf()->sputbackc(static_cast<char>(c));

in read_string_while. The character c does not have to be put back, because snextc first advances position, then returns the character at new position.
