Hi all,
This is a draft patch which hopefully improves the check whether a dir entry
should be ignored for that. It adds one feature: if you put a file '.noindex'
in a dir, the whole dir will be ignored for indexing. I find this very useful
for removing e.g. folders with spam messages from the indexing.
There is one maybe controversial change, namely that it ignores all dot-dirs;
this works fine for .notmuch and .nnmaildir (gnus), but maybe there is some
valid use case for having mail in dot-dirs. Maybe one of the IMAP-servers does
this? Not sure. Anyway, I can change that part.
If the overall approach is considered OK, I can make a new patch
Best wishes,
Dirk.
