Assume that you have done "git fetch origin" (or whatever master's upstream is). Do
git diff --name-only HEAD origin/master
You get the list of files that will need to be updated. Do
git diff --name-only
to get the list of files that have local changes. If this list shares some paths with the first list, these paths will very likely cause "git pull" to abort.
For a better check, I think you need to do "git read-tree -m" by yourself (to a temporary index file with --index-output) then you can examine that file and determine what file has changed compared to HEAD (and if the same file has local changes, git-pull will be aborted). You may need to read more in read-tree man page.
Ideally though, git-read-tree should be able to tell what paths are updated in "--dry-run -u" mode. But I don't think it's supported yet.
