(opascal-tab)
This function is obsolete since 24.4;
use `indent-for-tab-command' instead.
Indent the region, if Transient Mark mode is on and the region is active.
Otherwise, indent the current line or insert a TAB, depending on the
value of `opascal-tab-always-indents' and the current line position.
