Subject: 24.5; tcl.el: sending region to tcl process produces error

Steps to reproduce:
- Visit a Tcl boffer
- Start a new Tcl process using C-c C-t
- Select a region containing one or more Tcl commands
- Try and send it to the Tcl process using C-c C-x

Actual results:
- Emacs reports an error: "error in process filter: Text is read-only"
- No Tcl commands are sent to the Tcl process
- Further interaction with the Tcl process buffer becomes erratic

Expected results:
- The region should be sent to the Tcl process, and any commands should
be executed.
- The Tcl process buffer should interact normally, accepting new
manually entered commands and displaying their results.

From some experimenting and some helpful discussion on IRC, I found that
a very likely cause of the problem is the way in which Tcl mode tries to
erase the prompt in a process buffer.  Apparently it doesn't handle
read-only prompts correctly.
