dont truncate summary length anymore

make sure not partial (invalid) utf-8 sequences are written. The old logic
truncated by bytelen was wrong. It is too complex to implement it in a
correct way with git: it is not assured a commit message is UTF-8 encoded.

remove showlinecount and summarylen variables.
