patch: include flag-only file changes in "special" when filtering (issue5864) This patch fix the issue5864 (or maybe issue5865 too) which occurs during split (or I should say at the time of filtering the hunks in interactive mode) where user hits a not ending loop of "no changes to record". And it's not only the case for split it will happen in every interactive case for e.g. `hg commit -i` or `hg uncommit -i` After looking into code I found that when filtering we have some notation called "special" for the file headers which doesn't contain any hunk and just contain the header (for e.g. newly added empty file or deleted file) where the user cannot change the content of operation. And I think we can put this "flag-only" file change in that same bucket of "special". But I doubt a bit about the case when a file have flag change and atleast one hunk then user won't be able to separate the flag change from hunks. Changed test file reflect the fixed behaviour.
