This release fixes an issue which only affects users on case-insensitive
file systems and repositories which contain paths that differ only in
case. Such circumstances result in a segmentation fault in various git
commands.
From the release announcement¹
A malicious third-party can give a crafted "ssh://..." URL to an
unsuspecting victim, and an attempt to visit the URL can result in
any program that exists on the victim's machine being executed.
Such a URL could be placed in the .gitmodules file of a malicious
project, and an unsuspecting victim could be tricked into running
"git clone --recurse-submodules" to trigger the vulnerability.
Credits to find and fix the issue go to Brian Neel at GitLab, Joern
Schneeweisz of Recurity Labs and Jeff King at GitHub.

EL-5 has been EOL for several months now. We can drop all the
conditionals needed to build there, as well as some conditionals for
long-expired Fedora releases.
Without EL-5 we also no longer use the prebuilt documentation. Remove
these sources and simplify the gpg check for the remaining source.
Many years ago, the GPG signature file was included in the source list¹.
A compromise at kernel.org caused the tarballs to move to googlecode.com
for a number of releases and the signatures were not provided in an
easily downloaded format². When the source location was moved back to
kernel.org, the signature file had already been removed from the spec
file and was not re-added³.
There is an effort underway to make GPG signature verification a
requirement when upstream provides signatures⁴. Regardless of whether
this becomes a requirement in the packaging guidelines, verification of
upstream signatures makes good sense. It also makes the process easier
for git package maintainers, who are (or should be ;) doing this
manually for each upstream git release.
While adding the signatures to the source list, all non-upstream source
files were moved to Source10 and above. This should make it easier to
add new upstream source files in the future, avoiding the need for
tedious (and error-prone) renumbering of existing sources.
Remove the unused entry for Patch14 also.

Using https URL's for source files provides a little more security for
those downloading the code. Packagers, of course, should be verifying
the GPG signature files before pushing new releases to Fedora's source
cache¹.
While we're changing the source URL's, we might as well use the smaller
tar.xz files which upstream provides. (This requires minor adjustments
to the unpacking of prebuilt html and man tarballs; tar on el5 does not
know how to automatically filter via xz.)
¹ Replace .xz with .sign for the signatures, which are made against the
uncompressed tarballs.
