Subject: 23.0.60; delphi-mode: TAB should indent region in Transient Mark mode (with patch)
Date: Sun, 06 Sep 2009 00:13:32 -0400

The patch below makes delphi-mode indent the region when the TAB key
is pressed, whenever Transient Mark mode is enabled and the region is
active.  (This became standard behaviour with Emacs 23.1 but wasn't
automatically reflected by delphi-mode as it defines its own TAB-key
binding.)

I've tested this with different combinations of transient-mark-mode,
delphi-tab-always-indents and delphi-newline-always-indents and it
appears to work fine.

Changes:

(delphi-tab): Indent region when Transient Mark mode is enabled and
region is active; otherwise indent or insert TAB as usual.
(delphi-mode): Update description of TAB-key binding.
