Initially the libssh2 code was indented with tabs of 4 spaces. Some of
the recent commits converted the tabs to 4 spaces, which matched the initial indent size. Other commits converted the tabs to 8 spaces, this didn't match. All the code has been converted to 4 space indents. No changes to line lengths or actual code was performed. This is in preperation to my up coming non-blocking work so my commits should only be code changes and line lengths in the code I am working on.
