First Sunday

[Jesper Norgaard Welen]

There are a few instances in the tz database where a rule is using the
string "Sun<=7" rather than "Sun>=1" to mean the first Sunday in the
month. I would recommend using "Sun>=1", because I think it is clearer.
At least I confused "Sun<=7" with "Sun>=7" once when reading these
rules, which is quite a different thing.

In the africa file:
Rule	Algeria	1916	1919	-	Oct	Sun<=7	23:00s	0
-

In the antarctica file:
Rule	ArgAQ	1967	1968	-	Oct	Sun<=7	0:00	1:00
S
Rule	ArgAQ	1968	1969	-	Apr	Sun<=7	0:00	0

...
Rule	ArgAQ	1974	1976	-	Oct	Sun<=7	0:00	1:00
S
Rule	ArgAQ	1975	1977	-	Apr	Sun<=7	0:00	0
