        src/bin/sh: expand.c expand.h

Log Message:
When expanding a here-doc (NXHERE - the type with an unquoted end delim)
the output will not be further processed (at all) so there is no need
to escape magic chars in the output, and doing so leaves stray CTLESC
chars in the here doc text.  Not good.   So don't do that...

To save a strlen() of the result, to determine the size of the here doc,
make rmescapes() return the length of the resulting string (this isn't
needed for other uses, so didn't happen previously).
