* subversion - set LC_ALL for accurate command output parsing
When LC_ALL is not set, the output language of commands will differ based on locale. There
is a lot of history of trying to fix this. See the following pull requests:
https://github.com/ansible/ansible-modules-core/pull/4358https://github.com/ansible/ansible-modules-core/pull/4358
This patch attempts to fix this my setting LC_ALL to a UTF-8 locale. Setting LC_ALL to C reintroduces this bug https://github.com/ansible/ansible-modules-core/issues/4178.
I'm sure there are some problems I am not seeing with setting this to en_US.UTF-8, but that is
the only way I could find to fix this bug without reintriducing the bug mentioned above.
* Rather than setting locale, just check for matches before trying to get groups
This is a pragmatic solution to avoid the stack trace since setting the locale correctly
to ensure message parsing is accurate is problematic.
* Improve regexps for finding revision and URL
