t7502: test commit.status, --status and --no-status
Make sure that the status information:
- is shown as before without configuration nor command line option;
- is shown if commit.status is set to true and no command line option
is given, or --status is explicitly given;
- is not shown if commit.status is set to false and no command line
option is given, or --no-status is explicitly given.
Also make sure that the way lines taken from the custom --template appear
in the log message editor is not changed at all.
