Make it safer to normalize the line endings in a repository.
Files that had been commited with CRLF will be commited with LF.
The old way to normalize a repo was like this:
# Make sure that there are not untracked files
$ echo "* text=auto" >.gitattributes
$ git read-tree --empty
$ git add .
$ git commit -m "Introduce end-of-line normalization"
The user must make sure that there are no untracked files,
otherwise they would have been added and tracked from now on.
The new "add --renormalize" does not add untracked files:
$ echo "* text=auto" >.gitattributes
$ git add --renormalize .
$ git commit -m "Introduce end-of-line normalization"
Note that "git add --renormalize <pathspec>" is the short form for
"git add -u --renormalize <pathspec>".
While at it, document that the same renormalization may be needed,
whenever a clean filter is added or changed.

DESCRIPTION
warning (e.g., if you are manually performing operations on
submodules).
+--renormalize::
+ Apply the "clean" process freshly to all tracked files to
+ forcibly add them again to the index. This is useful after
+ changing `core.autocrlf` configuration or the `text` attribute
+ in order to correct files added with wrong CRLF/LF line endings.
+ This option implies `-u`.
+
--chmod=(+|-)x::
Override the executable bit of the added files. The executable
bit is only changed in the index, the files on disk are left
-------------------------------------------------
$ echo "* text=auto" >.gitattributes
-$ git read-tree --empty # Clean index, force re-scan of working directory
-$ git add .
+$ git add --renormalize .
$ git status # Show files that will be normalized
$ git commit -m "Introduce end-of-line normalization"
-------------------------------------------------
into a usable content by setting the filter.<driver>.required configuration
variable to `true`.
+Note: Whenever the clean filter is changed, the repo should be renormalized:
+$ git add --renormalize .
+
For example, in .gitattributes, you would assign the `filter`
attribute for paths.
