The Borland IDEs have long supported various "smart" indentation
features, which can each be individually turned on or off (see the third
one for the answer to your specific question):

* Auto indent mode - Positions the cursor under the first nonblank
  character of the preceding nonblank line when you press ENTER in
  the Code Editor.

* Smart tab - Tabs to the first non-whitespace character in the
  preceding line. If "Use tab character" is enabled, this option
  is off.

* Backspace unindents - Aligns the insertion point to the previous
  indentation level (outdents it) when you press BACKSPACE, if the
  cursor is on the first nonblank character of a line.

There are a number of other tab-related options as well.
