I have not read indentor's code, so I'll only comment about the example
replacement code.

My complaint is basically the same as my complaint about io_manip.
The example code looks like it discards the old fill character in favor
of a new one... and never sets it back.  I'll continue to hope that an
official implementation would not do such things.

I'll have to check that out, since I have no clue what it does
already...  But where can I find it?  Searching boost...
"Your search - marg_ostream - did not match any documents."
