I have some tags which begin "CD" followed by a number. For example
* Tagged Heading :CD123:
When I ask for a sparse tree of all tags beginning with "CD", I do
'C-c / T'
And ask for tags of
This doesn't return any of the tagged headlines, but this does:
Is this a bug, or my misunderstanding? Obviously this is no
show-stopper, I just make sure that all my regexp searches are in
case, but thought I'd check.
It may be a bug, and a misunderstanding.
1. I do downcase all tage before they are tested in the matcher.
2. This seems to indicate that I do want the matching to be case-
3. I do set case-fold-search to nil, which seems to contradict (2)
For now, I recommend to write all regexps with lower case letters.
I need to try to remember why I did not set case-fold-search.
I am pushing a fix today which will mkae sure that tags matching is
truly case insensitive. So that should make your old regexp work again.
