1bc992acac [PATCH] Fix confusing behaviour of update-cache --refresh on unmerged paths.
The "update-cache --refresh" command attempts refresh_entry()
on unmerged path, which results in as many "needs update" messages
as there are unmerged stages for that path.  This does not do
any harm to the working directory, but it is confusing.

Here is a fix.

9fec8b26ef [PATCH] Do not run useless show-diff on unmerged paths repeatedly.
When run on unmerged dircache, show-diff compares the working
file with each non-empty stage for that path.  Two out of three
times, this is not very helpful.  This patch makes it report the
unmergedness only once per each path and avoids running the
actual diff.

Upper layer SCMs like Cogito are expected to find out mode/SHA1
for each stage by using "show-files --stage" and run the diff
itself.  This would result in more sensible diffs.

taking shell metacharacters into account.  A malicious dircache
entry "foo 2>bar" (yes, a filename with space) would result in
creating a file called "bar" with the error message "diff: foo:

can be created as a result of a merge with tree from others.
