'the result' is a bit of a nebulous concept - exec() fills the output array
with whatever the called script/program *spat out on stdout*.
my fault was indeed thinking along such 'the result' lines - I did
not consider that stderr was not part of 'the result' and that most
programs seem to happily spit out their output to stderr (e.g. apache2ctl,
cvs, mysql to name a few that I was calling in the problem script) and yes
I'm still rather baffled as to why something like apache2ctl would
dump the string 'Syntax OK' to stderr - if ever there was some user feedback
that *didn't* represent an error it would be 'Syntax OK'.

ah so you got the the photo of me with "total f'ing noob"
tattooed on my forehead then?
obviously the photo is not of very good quality because the tattoo actually
says:
"this idiot is liable to write WITH when he means WITHOUT"
2 other people did successfully manage to translate the WITH to WITHOUT
based on the rest of what I wrote - thankfully :-)
