Fix #2087

If a user has the Powershell Community Extensions installed, it comes
with another command Expand-Archive that doesn't have a DestinationPath
argument, causing an error.

* Use --line-range instead of head in bat example

* README: extend preview section

When called with popup options, do not move to temp window.

The action takes place in the alternate screen so the offsets should
still be correct.

* No need to restore &wfw and &wfh when using popup window

Make sure that `extldflags` is quoted so that LDFLAGS containing spaces won't break the build command.
