The parsing done by the script is extremely naive :) It counts
the leading space in multi line comments as indentation which
it is not. Filtering each file through stripcmt first [1] gives a
somewhat different result:

# lines affected/ws-prefixed lines: 1045/28030
# files affected: 58/80

n: 19 #unchanged: already have TAB-based indentation
N: 2 #unchanged: already perfect
0: 1 #unchanged: no candidate lines
^: 6 #files changed to have all-spaces indentation
_: 52 #files changed to have TAB-based indentation

Although the result from the script is only a rough estimate,
excluding the largest entry of the 52 files (with 171 lines), the
average of the other 51 is just 15 lines pr file.  So for a few files
there will be large changes, but overall correcting the indentation
will not be an extremely invasive change.
