The above description does not seem to match what the patch does at
all, though.  Sent a wrong patch, possibly just the tip of a series,
when you needed to send more than one patches?  For example, the
header for the hunk -103,33 tells us that the file already has OPTIONS
section before this patch gets applied.

That reads well.

The original removed by the patch said "directories or patterns",
and I understand that this change is an attempt to say that the
command chooses between directories and patterns using the same
criteria as the "set" command, but the added "are interpreted the
same way as ..." in the middle interrupts the flow of thought the
sentence conveys.  To me, it looks like the first sentence gives
clear enough explanation of that already.

Broken indentation aside, I do not see why this change is needed.

These three lines are not technically incorrect, but is not written
in a way that helps readers.

Read these three lines a few times, pretending that you have never
used the sparse-checkout, and try to answer this question: "I am
giving a few arguments to the command using the cone mode.  Are they
taken as directories, or patterns?"

It is hard for me to guess what is being improved upon because I do
not have the preimage of this hunk, but the new text is much less
clear than "directories (in cone mode) or patterns (in non-cone
mode)" we saw earlier in the description for the 'add' command,
which would help us answer the question (answer: they are taken as
directories).

Thanks.
