Thanks.

One general comment about the doc strings:

> +(defvar-local comint-indirect-setup-function nil
> +  "Function to set up an indirect buffer.

here and elsewhere in the changes, please modify the first sentence of
the doc strings so that they don't sound too general.  "Set up an
indirect buffer" doesn't hint on the fact that this is for comint
buffers, not in general about indirect buffers.  The same problem
exists with many doc strings in these patches.
