  1. fix normalise_string to prevent issues when lexer->buflen == 0 

    This was flagged by either the memory sanitizer or the undefined
behavior sanitizer as an issue.

This commit changes the datatype of `i` to be `ssize_t` so that
`lexer->buflen - 1` becomes less than 0 when `lexer->buflen` == 0.
