Because people are very unlikely to think about "GnuPG version
compatibility".  They are likely to think about "version
compatibility" and perhaps just "compatibility".  Just put yourself
into the shoes of such a reader, and ask yourself what would you type
at Info-index's prompt.

If you remember the name of the section, you can usually use 'g',
since node names are usually very similar to section names.

My personal rule is to use capital letters in index entries only when
absolutely necessary.  It is not necessary with "gpg" or "gnupg".  The
above citation says something similar.

Does it mean the patch you sent is just part of the changes?
