From memory, inaccuracy possible

Thanks. just 1 fix:
After
git clone https://github.com/OpenXRay/xray-16.git --recurse-submodules
We don't need to do:
git submodule update --init --recursive

[drug007]

@q4a I left it just in case, but I wasn't sure it was useful, so it's fixed now.

Offtopic: what about using markdown instead of plain text?

[drug007]

@q4a, @Zegeri, and the others: please do not merge this PR before I rebase it to current head. If you think PR looks good just write LGTM (looks good to me) for example or make other sign.

Frankly we shouldn't merge any PR until it is rebased to the head. This easy rule makes history much more pleasant to work with.

[Xottab-DUTY]

@drug007 no need for this. There's no conflicts, so the rebase is unnecessary.

[drug007]

@Xottab-DUTY there is big need for this. Our repository history is awful due to this fact. Conflicts aren't the only reason to make rebase.
