ls-files: add eol diagnostics
When working in a cross-platform environment, a user may want to
check if text files are stored normalized in the repository and
if .gitattributes are set appropriately.
Make it possible to let Git show the line endings in the index and
in the working tree and the effective text/eol attributes.
The end of line ("eolinfo") are shown like this:
"-text" binary (or with bare CR) file
"none" text file without any EOL
"lf" text file with LF
"crlf" text file with CRLF
"mixed" text file with mixed line endings.
The effective text/eol attribute is one of these:
"", "-text", "text", "text=auto", "text eol=lf", "text eol=crlf"
git ls-files --eol gives an output like this:
i/none w/none attr/text=auto t/t5100/empty
i/-text w/-text attr/-text t/test-binary-2.png
i/lf w/lf attr/text eol=lf t/t5100/rfc2047-info-0007
i/lf w/crlf attr/text eol=crlf doit.bat
i/mixed w/mixed attr/ locale/XX.po
to show what eol convention is used in the data in the index ('i'),
and in the working tree ('w'), and what attribute is in effect,
for each path that is shown.
Add test cases in t0027.

Show <eolinfo> and <eolattr> of files.
|

<eolinfo> is the file content identification used by Git when

the "text" attribute is "auto" (or not set and core.autocrlf is not false).
|
||||
<eolinfo> is either "-text", "none", "lf", "crlf", "mixed" or "".

"" means the file is not a regular file, it is not in the index or
|

not accessable in the working tree.
|

|

<eolattr> is the attribute that is used when checking out or committing,
|
||||
it is either "", "-text", "text", "text=auto", "text eol=lf", "text eol=crlf".
|
||||
Note: Currently Git does not support "text=auto eol=lf" or "text=auto eol=crlf",

that may change in the future.
