Thanks, will queue.

This inherits an ancient breakage that was introduced to the --whitespace
option by 67dad68 (add -C[NUM] to git-am, 2007-02-08), in that you need to
give the next "git am" session the same option when you get a conflict and
need to restart.  We should fix this ancient breakage by recording the
miscellaneous options that we append to $git_apply_opt variable (we should
remove the use of "$dotest/whitespace" that is now a no-op but 67dad68 did
not remove).  That is a separate topic anyway, but the end result should:

 * Save the options in effect in $dotest/, just like "sign", "utf8" and
   "keep" are kept;

 * Upon command startup, read the saved options, and then let the command
   line options override them (which is not what the current code does, by
   the way);

so that you can give necessary --directory, --whitespace, -C etc. options
when you feed your series to "git-am", and after fixing up a rejected
patch, you can continue without typing the same set of options again.
