The idea is to defend against some adversary-in-the-middle attacks.
Also prefer git.savannah.gnu.org over its shorter alias, git.sv.gnu.org
to avoid a warning e.g., from git clone.
Also, drop any final ".git" suffix on the resulting URIs.
Inspired by Paul Eggert's nearly identical changes to coreutils.
Induced by running these commands:
git grep -l 'git clone git:'|xargs perl -pi -e \
's{(git clone) git://(\S+)/([^/]+)\b}{$1 https://$2/git/$3}'
git grep -l git.sv.gn \
|xargs perl -pi -e 's{git\.sv\.gnu}{git\.savannah\.gnu}'
perl -pi -e \
's{(url =) git://(\S+)/([^/.]+)(\.git)?\b}{$1 https://$2/git/$3}'\
.gitmodules
* .gitmodules: As above.
* HACKING: Likewise.
* README-hacking: Likewise.
* src/grep.c (main): Likewise.
