Hmm, is there really something that needs a new proposal and
opinions?
The way I read the flow in convert.c is:
convert_to_git() uses input_crlf_action() to figure out what
crlf_to_git() conversion is necessary.
input_crlf_action() looks at text_attr and says CRLF_BINARY when
it is CRLF_BINARY without looking at eol_attr at all.
text_attr above is ca.crlf_action in convert_to_git().
The whole ca.* comes from convert_attrs() inspecting attributes
on the incoming path.
convert_attrs() inspects "eol" and "text" attributes, among
others, and sets crlf_action by calling git_path_check_crlf().
git_path_check_crlf() looks at the 'text' attribute; if it is
set to false, it returns CRLF_BINARY.
crlf_to_git() when given crlf_action==CRLF_BINARY is a no-op.
So, with the above attributes where anything is eol=crlf by default
and in addition *.png is binary (which contains -text), we shouldn't
get any crlf munging. Am I reading/following the code incorrectly?
Puzzled....
