I don’t quite understand how command completion works.
Every time I bring previous command for editing, change something at the
beginning of line and press TAB, it deletes the rest of the line!
Is there a way to keep the rest of the line?
Is it designed behavior or what? (bug or feature?)

This is a known limitation. Powershell tab-completion works by using the
alternate end-of-line feature of the console subsystem just like cmd.exe. As
a consequence, it suffers from some of the same limitations. We're planning
to fix this in a future release.
