I see. Well, stripl.sed does get rid of 195 blank lines, but just glancing
at a hex dump, only those which have no whitespace on them (a number seem
to have a single space before \n -- leftovers from cpp'ing #include
dxconfig.h into dxmdf.src it appears).
Fiddling around with it for a sec, this seems to do the job:
/^ *$/{
N
/^ *\n *$/D
}
though I'd want someone that knows sed to check that. This cleans out 521
blank lines, and the empty space up-top is gone.
Patch attached.
