That may be true.
By the way, "git checkout --conflict=<style>" is a short-hand for
"git checkout --merge --conflict=<style>" and it is quite useful not
just in the said case of "oops, I cannot read this conflict with the
'merge' style---let's switch to 'diff3' style". After starting to
attempt resolving the conflict, sometimes I become unsure if the
resolution I've been working on is correct, and want to start from
scratch. In such a case, even without switching the style to a
different one, "git checkout --merge" to discard the changes I made
in the working tree file and reproduce the auto-merged state with
conflict markers, is a good tool in your toolbox to know (being able
to give a different conflict style is merely a natural extension of
the feature).
Perhaps in Documentation/git-merge.txt there can be a mention of
When you really screwed up your resolution, you could use
"git checkout --merge -- $paths" to revert selected paths
back to the state just before the auto-merge gave up and
asked your help in resolving. The --conflict=<style> option
can be used instead of the "--merge" option in the command
to use a different conflict marking style. See
git-checkout[1] for details.
or something along that line. People who are unware of "checkout -m"
in such a situation may run "git reset --hard" and redo the whole
merge from scratch, but you do not have to discard the resolution
you made in other paths successfully only to redo a few files that
you botched.
