You can make it work if you think step-by-step.  First, this is what
you want to run:

	sh -c 'git log --format="..." "$@" | sed "s/@\S*//"' -

so that "git euguess master..next" would turn into

	sh -c 'git log --format="..." "$@" | sed "s/@\S*//"' - master..next

Now, you want to wrap it into an alias, i.e.

	[alias]
        	euguess = "!sh -c ..."

That ... part is read by our configuration reader, so you need to
quote the double quotes and backslashes with backslash, which would
give you something like:

	[alias]
		euguess = "!sh -c 'git log --format=\"%h %ae %s\" --date=short \"$@\" | sed \"s/@\\S*//\"' -"
