SCRIPTS: git-show-backports: do not truncate git-show output

git-show-backports lists a git-show command which can be used to inspect
all commits subject to backport. This command specifies formatting
option to reproduce default git-show output, especially for commit
messages indented with 4 spaces character. However, it also add wrapping
on message line longer than 72 characters. This reduce lisibility of
messages where large info are written such as backtraces.

Improve this by changing git-show format option. Use a limit value of 0
to disable wrapping while preserving indentation.

This could be backported to every stable version to simplify backporting
process.
