And likewise for 'git fetch -h', a few lines below that.
Testing with a few older 'git' binaries that I happen to have lying around:
$ git clone -h 2>&1 | grep depth
1.4.4:
1.5.0.rc4:
Usage: .../bin/git-clone [--template=<template_directory>] [--reference
<reference-repo>] [--bare] [-l [-s]] [-q] [-u <upload-pack>] [--origin <name>]
[--depth <n>] [-n] <repo> [<dir>]
2.22.0:
--depth <depth> create a shallow clone of that depth
2.43.0:
--[no-]depth <depth> create a shallow clone of that depth
$ git fetch -h 2>&1 | grep depth
1.6.3.2:
1.7.1:
--depth <DEPTH> deepen history of shallow clone
2.22.0:
--depth <depth> deepen history of shallow clone
2.43.0:
--[no-]depth <depth> deepen history of shallow clone
So, the --depth option
- in 'git clone' was introduced before git 1.5.0.rc4 (2007-02-08),
- in 'git fetch' was introduced before git 1.7.1 (2010-04-24).
We can safely assume that no one is using 'git' binaries from 2010 or older
for active development. Thus I'm removing these feature checks:

* top/bootstrap-funclib.sh (prepare_GNULIB_SRCDIR): Assume that
'git clone' and 'git fetch' support the --depth option.
