Re: [PATCH v8 07/10] convert: unify the "auto" handling of CRLF

RFH, the normalization as descrived in Documentation/gitattributes.txt
does not work anymore:


From a clean working directory:

-------------------------------------------------
$ echo "* text=auto" >.gitattributes
$ rm .git/index     # Remove the index to force Git to
$ git reset         # re-scan the working directory
$ git status        # Show files that will be normalized
$ git add -u
$ git add .gitattributes
$ git commit -m "Introduce end-of-line normalization"
-------------------------------------------------


I have different ideas, how a a normalizatio  can be done:

A) 
-------------------------------------------------
$ echo "* text=auto" >.gitattributes
$ rm .git/index
$ git add .
$ git status        # Show files that will be normalized
$ git commit -m "Introduce end-of-line normalization"
-------------------------------------------------

B)
$ echo "* text=auto" >.gitattributes &&
$ git add .gitattributes &&
$ git ls-files --eol | egrep '^i/(crlf|mixed).*attr/(text|auto)' | ( TAB=$(printf "\t") ; sed -e "s/.*$TAB/dos2unix /" ) >/tmp/$$ &&
$ /bin/sh /tmp/$$ &&
$ rm -f /tmp/$$ &&
$ git add -u &&
$ git commit -m "Introduce end-of-line normalization"

C) 
Teach "git add" to learn --renormalize and then
-------------------------------------------------
$ echo "* text=auto" >.gitattributes
$ git add -u --renormalize
$ git add .gitattributes
$ git commit -m "Introduce end-of-line normalization"
-------------------------------------------------

(None of them is really tested)

A) may loose the execute bit
B) dos2unix is not installed everywhere (like Mac OS)
C) seems to most attractive, but I couldn't find out how to forward
   options from "git add" into convert.c


Any help is appreciated.
