tar update problem

[Kamran]

Hi all

Recently I have noticed that Win10-File-history not working
for me. Somehow it is missing large part of my directory-tree.
One guess is that tree is too deep. But that is another story.

I tried to use "tar --update" to have some rudimentary backup,
with some exclusions.

Apparently it worked fine. But later it is found that any
folder excluded by using "--exclude-tag-under=FILE" or
"--exclude-ignore-recursive=FILE" is excluded only first
time. Hence, failing my idea.

$ uname -a
CYGWIN_NT-10.0-19045 yark 3.4.6-1.x86_64 2023-02-14 13:23 UTC x86_64 Cygwin

$ tar --version
tar (GNU tar) 1.34
Packaged by Cygwin (1.34-1)

Sure that it is tar bug. But if not I am open to
suggestions.
