Subject: Don't report dives as they are parsed: sort them at the end and report them then
X-Git-Url: http://git.tdb.fi/?a=commitdiff_plain;h=048a5a2b32c0638708ca4779007f9e33226d54f4;p=ext%2Fsubsurface.git

Don't report dives as they are parsed: sort them at the end and report them then

This makes it much easier to see the duplicates, but more importantly,
we do need to actually save the dives off to do any real work with them.

Also, require a verbosity level of 1 (-v) to show all the samples.
While (-vv) shows unparsed entries.
