rebase -i: more graceful handling of invalid commands

Browse source 
Currently, when there is an invalid command, the rest of the line is
still treated as if the command had been valid, i.e. rebase -i attempts
to produce a patch, using the next argument as a SHA1 name. If there is
no next argument or an invalid one, very confusing error messages
appear (the line was '.'; path to git-rebase-todo substituted):

Unknown command: .
fatal: ambiguous argument 'Please fix this in the file $somefile.':
unknown revision or path not in the working tree.
Use '--' to separate paths from revisions
fatal: Not a valid object name Please fix this in the file $somefile.
fatal: bad revision 'Please fix this in the file $somefile.'

Instead, verify the validity of the remaining line and error out earlier
if necessary.
