make checksum update smarter
Via --pkgver=...
and --updpkgsums
one can currently update the checksums used in the PKGBUILD
.
It would be good if the behavior regarding checksums gets a little smarter, i.e. in the following ways:
- only update checksums for new entries
- (auto?) update checksums for new source entries
- allow updating single checksums
All while making the current behavior available via a switch or mode to the option.
