#2 truncate long reports

[Norman Vine]

syncmail currently truncates long reports from any
individual file but can still spew long reports if many
files are committed at once. This simple patch adds
a total lines counter that will truncate the total
message length. I arbritrarily used the same length
to truncate at as was used for an individual file, this
can easily be changed. All files changed will still be
reported but the details will be omitted for all files
after the chosen truncation length. This code is
untested

This would be a great help to mailing list administrators
who currently have to deal with removing all excess size
mails...
