The main difference between back-to-indentation and beginning-of-line-text 
is that back-to-indentation ignores the fill-prefix.  With a buffer with 
the following two lines:

     1234
> > > > 5678

with point on "4:
- move-beginning-of-line moves point to the beginning of the line
- back-to-indentation moves point to "1"
- beginning-of-line-text moves point to "1"

with point on "8":
- move-beginning-of-line moves point to the beginning of the line
- back-to-indentation moves point to the beginning of the line
- beginning-of-line-text moves point to "5"
