I've made the same mistake myself many times. I really wish gdb would
interact over /dev/tty by default. The perl debugger does this, and I
find it quite handy. But I've never managed to make gdb do it. Maybe
there is an option I've missed[1].
The downside of what approach, though, is that you cannot restart the
program reliably from within the debugger (it cannot know how to
re-set-up the descriptors). So you have to quit and restart, which loses
any breakpoints, etc.

[1] Having written that, I'm not sure I ever tried a script that does
something like:
program=$1; shift
exec 3<&0
exec 4>&1
gdb </dev/tty >/dev/tty -ex "set args <&3 >&4 gdb $*" "$program"
I think that would work, but it does screw up quoting/whitespace in
your arguments.
