[mkgmap-dev] [PATCH] make tdbfile (fully) the default and remove --tdb-v3

Hi

No it isn't yet, and that patch doesn't make tdbfile a default
in a way that would affect its use with --index.

Still, you make a good point.

We shall have to think about how this should work. I don't really
like using tdbfile with index to mean create a "desktop" index anyway.

So either we should create the gmapsupp index if that option is given
and the desktop index otherwise or create both if the gmapsupp option
is given.

Its always possible to have --index=gps,... but I don't like that
much either.

It does use more on average, but peak memory usage may not be different, 
since the peak memory use only occurs during one
sorting operation.

So maybe it is not so much of a problem as I thought.

Certainly it would be possible to fix it so that it doesn't use
any more memory.
