These programs don't need to read files in the current directory: GotMArc loads in memory some files at load time, at that point no other accesses to "." are needed.

avoids the "Wide character in print at ./mkindex line 152, <> line 2751" warnings.

pick up the *latest* From/Date for the indexes, not what happened to be the last mail rendered in that thread. spotted by stsp@

reminded by semarie@, thanks!

we can't use the tmppath pledge promise as File::Temp checks whether /tmp exists. We could unveil("/tmp", "r") and use `tmppath', but it seem misleading. (noticed after semarie@ reminded me of `tmppath')

there's little point to use pledge/unveil and then allow the program to modify itself...
