Hallo!
There is an option in git client (core.autocrlf). According to the option, all the sources should be committed to Git in Linux end-of-line style. According to Stash plugin API, there is not way to check EOL style of the files, as all the committed data is passed line-by-line, already splitted and already without EOL symbols.
How it is suggested to perform this restirction in Stash?
