The last time I checked, EGit does not set this by default. ECLIPSE Oxygen
3A/EGit-JGit 5.0.1, when running on Windows, creates core.filemode=false,
core.logallrefupdates=true, repositoryformatversion=0, symlinks=false. Some
SourceTree versions that predate the newer SourceTreeApp are somewhat stuck
on older embedded versions of git, but that may not be relevant. Personally,
I would seriously like to drop core.autocrlf and just have everyone on LF
EOL characters. I get frequently burnt by this despite knowing better.

Cheers,
Randall
