I don't think it would be very hard to write `>' (redirect) and `>>'
(redirect-append) commands for gdb.  Maybe you could even have a `|'
command that would pipe output through another process (this might be
harder due to portability constraints).

The easiest way to do this would be to have prefix commands.  For
instance `> file command' would run command with output redirected to
file.  `> file' would redirect output for all subsequence command
lines.  Plain `>' would then stop redirecting the output.

Likewise for `>>'.  Something like `|' would probably need a slightly
different syntax (for instance simply disallow a trailing gdb
command).

Using a prefix command feels a bit strange, but I implementation-wise
is probaby much, much easier.
