Subject: [PATCH] Several changes to the gethostname module:

. rename the function to main'gethostname, so it can be called unqualified,
. strip the trailing \0 character, closes PR # bin/1084,
. a better way to express an insane long string.

Submitted by:	Giles Lean <giles@topaz.nemeton.com.au> (except the 1st)
