Jeff King 0a8a16ade6 parse-options: drop OPT_DATE() 
There are no users of OPT_DATE except for test-parse-options; its
only caller went away in 27ec394a97 (prune: introduce OPT_EXPIRY_DATE()
and use it, 2013-04-25).

It also has a bug: it does not specify PARSE_OPT_NONEG, but its callback
does not respect the "unset" flag, and will feed NULL to approxidate()
and segfault. Probably this should be marked with NONEG, or the callback
should set the timestamp to some sentinel value (e.g,. "0", or
"(time_t)-1").

But since there are no callers, deleting it means we don't even have to
think about what the right behavior should be.

cat >expect <<\EOF
usage: test-tool parse-options <options>
A helper function for the parse-options API.
--yes get a boolean
-D, --no-doubt begins with 'no-'
-B, --no-fear be brave
-b, --boolean increment by one
-4, --or4 bitwise-or boolean with ...0100
--neg-or4 same as --no-or4
-i, --integer <n> get a integer
-j <n> get a integer, too
-m, --magnitude <n> get a magnitude
--set23 set integer to 23
-L, --length <str> get length of <str>
-F, --file <file> set file to <file>
String options
-s, --string <string>
get a string
--string2 <str> get another string
--st <st> get another string (pervert ordering)
-o <str> get another string
--list <str> add str to list
Magic arguments
--quux means --quux
-NUM set integer to NUM
+ same as -b
--ambiguous positive ambiguity
--no-ambiguous negative ambiguity
Standard options
--abbrev[=<n>] use <n> digits to display SHA-1s
-v, --verbose be verbose
-n, --dry-run dry run
-q, --quiet be quiet
--expect <string> expected output in the variable dump
