When working in a cross-platform environment, a user wants 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:
"binary" binary file
"text-no-eol" text file without any EOL
"text-lf" text file with LF
"text-crlf" text file with CRLF
"text-crlf-lf" text file with mixed line endings.
The effective text/eol attribute is one of these:
"", "-text", "text", "text=auto", "eol=lf", "eol=crlf"
git ls-files --eol gives an output like this:
i/text-no-eol w/text-no-eol attr/text=auto t/t5100/empty
i/binary w/binary attr/-text t/test-binary-2.png
i/text-lf w/text-lf attr/eol=lf t/t5100/rfc2047-info-0007
i/text-lf w/text-crlf attr/eol=crlf doit.bat
i/text-crlf-lf w/text-crlf-lf attr/ locale/XX.po
Note that the output is meant to be human-readable and may change.

Thanks everybody for contributing to this patch, expecially Eric Sunshine
Changes since v5:
- shell here document without substitions (Thanks Eric)
Changes since v4:
- gather_convert_stats_ascii() is static (Thanks Ramsay)
Changes since v3:
- typos (thanks for careful review)
- Remove un-intended changes in check-attr.c (they should not have been there)
- Improved t0027 (Thanks Eric)
Changes since v2:
- Major rework
- New prefix, more common to what we use in Git (i/, w/ attr/)
- Only one option: git ls-files --eol (may be combined with -s or -o or -d
- Simplify the diagnostics: either the file is binary or text
As empty files are not binary, they are text-no-eol
- Test cases in t0027
