fix extra whitespace in rebased log messages
Trim leading and trailing whitespace from log messages when creating commits. Fixes a rebase issue but should be a good idea in general.
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)
