Alexander, thanks for your new review, I thought about all topics you
mentioned, but guessed the wrong way as I see now.

Thought that use by default bash if it exists by default is much
better. Anyway changed it.

Thought that if the commands are clear and no need to point view
on it than it should be abbreviated. Anyway changed it.

Thought that upper globals were under "if" and better not to mess
with it. Also the part of upper code is not build part. Anyway changed.

Ok, sure.

Ok, I'll provide more information on it.

Thought that 4 places is not good decission to comment with common
message, thought that blame will be much better to investigate the
change. Anyway added.

Right, I thought the same, but from the other hand thought that
if not disscussed than already correct. Changed it.
