It sounds like the real issue here is that you are interpreting
"recursively" to mean "globbing".  Your original complaint seemed to
be a surprise that "git rm book/\*.asc" would delete all of the files
in the directory "book" that ended in .asc, even without the -r flag.

That's because the operation of matching *.asc is considered
"globbing".  Now if there were directories whose name ended in .asc,
then they would only be deleted if the -r flag is given.  Deleting
directories and their contents is what is considered "recursive
removal".

That's not particularly surprising to me as a long-time Unix/Linux
user/developer, since that's how things work in Unix/Linux:

% touch 1.d 2.d ; mkdir 3.d 4.d
% /bin/ls
1.d  2.d  3.d  4.d
% rm -r *.d
% touch 1.d 2.d ; mkdir 3.d 4.d
% rm *.d
rm: cannot remove '3.d': Is a directory
rm: cannot remove '4.d': Is a directory

I'm going to guess that you don't come from a Unix background?
