Switch to alternate screen buffer

[Bertram Scharpf]

Hi,

this is difficult to google for.

In a terminal window I oftenly pipe some progams output to vim or to
less:

  $ someprg | vim -

When the program fails and outputs an error message to stderr this will
be overwritten by Vim.

I know from some old Linux installations that Less and Vim are able to
switch to an alternate screen buffer. They use the escape sequences
"\e[?1049h" and "\e[?1049l" to switch back respectively.

How can I activate this in FreeBSD?

Thanks in advance.

Bertram
