000_bash_completion_compat.bash sourced last in some locales

[liskin]

Describe the bug

Scripts in /etc/bash_completion.d/ often rely on the compatibility stuff like the have function but some locales order numbers last, so the compat stuff isn't available.

To reproduce

1. install something that relies on have being available, such as pmount 0.9.23-7.1 in Debian
2. LANG=cs_CZ.UTF-8 bash

Expected behavior

no errors, as opposed to bash: have: příkaz nenalezen (which means "command not found")

Versions (please complete the following information)

• Operating system name/distribution and version: Debian testing (as of 2024-06-03)
• bash version, echo "$BASH_VERSION": 5.2.21(1)-release
• bash-completion version, (IFS=.; echo "${BASH_COMPLETION_VERSINFO[*]}"): 2.14.0

Additional context

This glob:

bash-completion/bash_completion

Line 3323 in 35293af

for _comp__init_file in "$_comp__init_compat_dir"/*; do
