Palli, grep is case sensitive unless you call it with -i. Git for Windows includes openssl. Julia includes a bundled copy of git on Windows, but does not use it any more on 0.5 and I plan to remove it from the default binaries before release. On master we use libgit2, which uses the OS crypto libraries on Windows and Mac. To make https work in libgit2, we do include a copy of openssl on Linux. We may decide to change this to mbedtls since its license status is clearer.
The mac binaries of Julia also bundle a source build of command line git for the time being, though someone would have to check what that's using for https.
