s-parse is working, but emitting a spurious error

[timbarnes]

s-parse (c -- ) takes a string from the user and stores it in the tmp buffer. It is working correctly in the sense that it does read and save the string.

However, it emits an error from $interpret, stating "token not recognized", and showing the string that has been read. This suggests that s-parse failed to consume the string, i.e. failed to update >in, causing the parser to re-examine the string as a token.

s-parse needed to update the >in pointer.
