I think you are giving up on this, and I do not think that is

OK.

Now you (not you the author of the document, but figuratively "any
reader of this document") must have read all the four before this
point ;-) To put it differently, your reading of the above four
bullets are incomplete unless you read this too.
Typofix: "pargraph" -> "paragraph".
In any case, I cannot guess what 'also include the case of a leaning
slash' wants to say. Perhaps
Note that the above rule means you cannot easily say "a file
whose name contains 'hello' and in this directory only, not in
its subdirectories." because a pattern 'hello.*' does not have
any slash. To work around this limitation, you can prepend
your pattern with a slash, i.e. '/hello.*'; the pattern now
matches 'hello.txt', 'hello.c' but not 'a/hello.java'.
as the third point of the above paragraph (the first is about a
pattern without a slash, the second "Otherwise" is about a pattern
with one or more slashes, and the new "Note that" becomes the
third) may make it easier to follow and keep your "each bullet point
is independent".
