Do not skip saving for all "errors", e.g. "Permission denied"

[blueyed]

bup save should not get skipped (always) when there are errors in bup index, because these might be irrelevant and should not prevent the whole backup from being saved, e.g.: read Linux attr: [Errno 13] Permission denied might happen when you've saved some file using sudo in $HOME (and you backup without using sudo).

For some reason the file in question has odd permissions:

% ls -l ...
---------- 1 user user 21K Sep 16 13:45 /home/user/.local/share/vim/undo/...

indeed. maybe we shouldn't skip save ever? or should we have a --force option?

[blueyed]

Yes, I would not skip it by default.

A config option like --dont-save-on-index-error (but shorter, and maybe more generic like --halt-on-errors) would be useful then though.
Maybe in the same context something like "--skip-save", which would be useful when you want to test how much gets indexed, without saving.

agreed. i am not even sure we need an option at all after all.
