[PATCH] man page: redirection operators: fix swapped stdin/stdout

[Forest <forestix@xxxxxxxxx>]

The Redirections section incorrectly claimed that <& replaces stdout
and >& replaces stdin. Swapped them to make it read correctly.

Both errors were followed by extra text that looked like remains of a
mostly-deleted sentence. Removed those.
