[TxMt] Persistent Includes

I'm not sure how to put this without sounding like a demanding ingrate, but here goes...

I've been using Brad Choate's persistent include commands since the day they came out, because they are brilliant for my way of working. But (here it comes) they would be so much more brilliant still if it was possible to update any files selected in the project drawer whenever an included file was changed.

I know about TM_SELECTED_FILES, but I can't see how to apply a command to all of them in place. The only thing I could think of involved creating temporary files, which doesn't seem the right way to be going about this.

Any suggestions?
