[PATCH] clang-replace: Delete change description files

[Stefanus Du Toit]

  Specific comments down below.

  I really think this should be an option that's turned off by default! Removing files is fine if this is being done as part of some other tool (e.g. from cpp11-migrate) but for someone running this on the command line it could be quite a surprise...

Do you really want to delete the files if this failed?

And likewise for this. Seems to me they should only be removed if all of the operations succeeded. As a bonus, then you don't need ScopedFileRemover anymore!

Do you really need a set here? I assume that collectReplacementsFromDirectory will never encounter the same file twice, so you might as well just use a vector and avoid the overhead of using a set.
