It's not clear to me where you want to move it to; can you suggest a
patch?
One can do so like this:
git clone git://git.sv.gnu.org/bash.git
cd bash
git checkout devel
# edit/test cycle:
vi doc/bash.1
man doc/bash.1
... repeat as necessary
# get a patch:
git diff >patch
Here's a patch that does some modifying without moving, as a starting
point. It can be applied with "patch -p1 </path/to/patch".
Hope that helps,
Jonathan
