tog: don't clear diff view contents when indicating diff progress
this is much easier on the eyes when moving through diffs
be less clever: don't nest 'case' inside if (...)
no functional change
got_error_set_errno: take a char arg to pass to got_error_prefix_errno
$> got rm a got: : No such file or directory becomes $> got rm a got: /path/to/a: No such file or directory
got_error_from_errno -> got_error_prefix_errno
also add got_error_prefix_errno2 and got_error_prefix_errno3 which should hopefully all be merged into a single function with variadic args (but can't alloc mem)
