Recently "git diff --check" learned to detect new trailing blank lines
just like "git apply --whitespace" does. However this check should not
trigger unconditionally. This patch makes it honor the whitespace
settings from core.whitespace and gitattributes.

This new error mode allows a line to have a carriage return at the
end of the line when checking and fixing trailing whitespace errors.
Some people like to keep CRLF line ending recorded in the repository,
and still want to take advantage of the automated trailing whitespace
stripping. We still show ^M in the diff output piped to "less" to
remind them that they do have the CR at the end, but these carriage
return characters at the end are no longer flagged as errors.

The `core.whitespace` configuration variable allows you to define what
`diff` and `apply` should consider whitespace errors for all paths in
the project (See gitlink:git-config[1]). This attribute gives you finer
control per path.
For example, if you have these in the .gitattributes:
frotz whitespace
nitfol -whitespace
xyzzy whitespace=-trailing
all types of whitespace problems known to git are noticed in path 'frotz'
(i.e. diff shows them in diff.whitespace color, and apply warns about
them), no whitespace problem is noticed in path 'nitfol', and the
default types of whitespace problems except "trailing whitespace" are
noticed for path 'xyzzy'. A project with mixed Python and C might want
to have:
*.c whitespace
*.py whitespace=-indent-with-non-tab
in its toplevel .gitattributes file.
