Obsolete historic tz change for Libya

[Jesper Norgaard Welen]

In the timezone rules for Libya, it seems to me there is an obsolete
timezone change, at 1.st October 1990 at 0:00, because the Libya Rule is
only used in country Libya until 4.th. of May 1990:

Rule	Libya	1987	1989	-	Apr	 1	0:00	1:00
S
Rule	Libya	1987	1990	-	Oct	 1	0:00	0
-
# Zone	NAME		GMTOFF	RULES	FORMAT	[UNTIL]
Zone	Africa/Tripoli	0:52:44 -	LMT	1920
			1:00	Libya	CE%sT	1959
			2:00	-	EET	1982
			1:00	Libya	CE%sT	1990 May  4
# The following entries are all from Shanks;
# the IATA SSIM data contain some obvious errors.
			2:00	-	EET	1996 Sep 30
			1:00	-	CET	1997 Apr  4
			1:00	1:00	CEST	1997 Oct  4
			2:00	-	EET

Therefore I suggest that the timezone rule be corrected to
Rule	Libya	1987	1989	-	Oct	 1	0:00	0

This is not a big problem, but might induce some confusion in the reader
of the tz database. If there is any other reason to keep this line,
please state why.

Jesper
