Make it possible to show the line endings of files.
Files which are staged and/or files in the working tree:
git ls-files --eol-staged
git ls-files --eol-worktree
Both will show an output like this:
empty empty_file
bin binary_file_or_with_cr_handled_as_binary
txt-crlf text_file_with_crlf
txt-mix text_file_with_crlf_and_lf
txt-lf text_file_with_lf
txt text_file_with_no_eol_at_all
Implementation details:
Make struct text_stat, is_binary() and gather_stats() from convert.c
public, add a new function get_convert_stats_ascii() and use it
in and use them in ls-files.
git ls-files --eol-staged will give a line like this:
