Refuse to perform the conversion for mixed-EOL files. The CRLF->LF filter is left as-is, as that conversion is considered to be normalization by git and should force a conversion of the line endings.
0cf77103	2013-08-26T23:17:07	Start of filter API + git_blob_filtered_content This begins the process of exposing git_filter objects to the public API. This includes: * new public type and API for `git_buffer` through which an allocated buffer can be passed to the user * new API `git_blob_filtered_content` * make the git_filter type and GIT_FILTER_TO_... constants public
3658e81e	2013-03-25T14:20:07	Move crlf conversion into buf_text This adds crlf/lf conversion functions into buf_text with more efficient implementations that bypass the high level buffer functions. They attempt to minimize the number of reallocations done and they directly write the buffer data as needed if they know that there is enough memory allocated to memcpy data. Tests are added for these new functions. The crlf.c code is updated to use the new functions. Removed the include of buf_text.h from filter.h and just include it more narrowly in the places that need it.
5e5848eb	2013-02-14T17:25:10	Change similarity metric to sampled hashes This moves the similarity metric code out of buf_text and into a new file. Also, this implements a different approach to similarity measurement based on a Rabin-Karp rolling hash where we only keep the top 100 and bottom 100 hashes. In theory, that should be sufficient samples to given a fairly accurate measurement while limiting the amount of data we keep for file signatures no matter how large the file is.
9c454b00	2013-01-11T22:13:02	Initial implementation of similarity scoring algo This adds a new `git_buf_text_hashsig` type and functions to generate these hash signatures and compare them to give a similarity score. This can be plugged into diff similarity scoring.
0d65acad	2013-01-11T11:24:26	Match binary file check of core git in diff Core git just looks for NUL bytes in files when deciding about is-binary inside diff (although it uses a better algorithm in checkout, when deciding if CRLF conversion should be done). Libgit2 was using the better algorithm in both places, but that is causing some confusion. For now, this makes diff just look for NUL bytes to decide if a file is binary by content in diff.

7bf87ab6	2012-11-28T09:58:48	Consolidate text buffer functions There are many scattered functions that look into the contents of buffers to do various text manipulations (such as escaping or unescaping data, calculating text stats, guessing if content is binary, etc). This groups all those functions together into a new file and converts the code to use that. This has two enhancements to existing functionality. The old text stats function is significantly rewritten and the BOM detection code was extended (although largely we can't deal with anything other than a UTF8 BOM).
