rebase -i: style fixes and minor cleanups
This patch indents ";;" consistently with the rest of git's shell scripts, and makes sure that ";;" are before each "esac". It introduces a helper function "has_action", to make it easier to read the intentions of the code. Errors from "git rev-parse --verify" are no longer ignored. Spaces are quoted using single quotes instead of a backslash, for readability. A "test $preserve=f" (missing spaces) was fixed; hashes are no longer written to "$DOTEST"/rewritten/ unnecessarily. We used to quote the message for a squash, only to have "echo" unquote it. Now we use "printf" and do not need to quote to start with.
