override the default pager on Windows if not found

If the pager is set to "less", the default, and we cannot find "less"
on the PATH, fall back to "more", a Windows builtin.

It would be cleaner for myclirc to have some kind of "pager = auto"
setting but it is likely too late for that.

Addresses issue #1260 .
