Follow-up on pull request #16 this change refactors and combines the highlight and fuzzy highlight patches into one highlight function. Overall it does not make any sense using: - fuzzy highlighting when exact matching is used or - exact highlighting when fuzzy matching is used As such it makes sense to combine the two such that: - exact highlighting is used when exact matching is used and - fuzzy highlighting is used when fuzzy matching is used The FUZZYHIGHLIGHT_PATCH toggle has been removed in favour of HIGHLIGHT_PATCH. The FUZZYMATCH_PATCH toggle controls whether fuzzy matching is enabled. Enable both FUZZYMATCH_PATCH and HIGHLIGHT_PATCH to enable fuzzy highlighting. Additionally the fuzzy highlight patch only supported single-byte characters and would break when encountering multi-byte UTF-8 characters. This was reported ref. #24. This refactoring includes a change to work out the UTF-8 character length for a given character rather than assuming that every character uses one byte.
