In order to allow custom processing of the option, for example a "command mode" option that also has an argument, it would be nice to use OPTION_CALLBACK and not have to rewrite the extra check on incompatible options. In other words, making the processing of the option orthogonal to the "only one of these" behavior provided by OPTION_CMDMODE. Add a new flag that takes care of the check, and modify OPT_CMDMODE to use it together with OPTION_SET_INT. The new flag still requires that the option value points to an int, but any OPTION_* value can be specified as long as it does not require a non-int type for opt->value.

Unfortunately the suggestion is somewhat misguided; for example, the output "git am --show-current-patch" cannot be passed to "git apply" if it is encoded as quoted-printable or base64. To simplify worktree operations and to avoid that users poke into .git, it would be better if "git am" also provided a mode that copies .git/rebase-merge/patch to stdout. One possibility could be to have completely separate options, introducing for example --show-current-message (for .git/rebase-apply/NNNN) and --show-current-diff (for .git/rebase-apply/patch), while possibly deprecating --show-current-patch. That would even remove the need for the first two patches in the series. However, the long common prefix would have prevented using an abbreviated option such as "--show". Therefore, I chose instead to add a string argument to --show-current-patch. The new argument is optional, so that "git am --show-current-patch"'s behavior remains backwards-compatible. The next choice to make is how to handle multiple --show-current-patch options. Right now, something like "git am --abort --show-current-patch" is rejected, and the previous suggestion would likewise have naturally rejected a command line like git am --show-current-message --show-current-diff Therefore, I decided to also reject for example git am --show-current-patch=diff --show-current-patch=raw In other words the whole of --show-current-patch=xxx (including the optional argument) is treated as the command mode. I found this to be more consistent and intuitive, even though it differs from the usual "last one wins" semantics of the git command line. Add the code to parse submodes based on the above design, where for now "raw" is the only valid submode. "raw" prints the full e-mail message just like "git am --show-current-patch".
