parsedate.3: add an item in BUGS noting the weirdness of "next"
The real purpose of this commit is to supply the following message
which should be used for the immediately previous commit, replacing
its commit message (the two are similar, but definitely not the
same). With thanks to gdt@ for pointing out one of the (many) errors
in the previous message (and noting others I had already seen).
----
Make parsedate handle "12 noon" and "12 midnight" (including when the
time given is "12:00" or "12:00:00") - but only for exactly 12 o'clock.
"12:00:01" is am or pm, not noon or midnight.
"12 am" remains as an alias for "12 midnight", and "12 pm" for noon,
though both are strictly (pedanticly) invalid (and meaningless.)
Note that "12 midnight" (or "12 am") means 00:00:00 (ie: midnight at
the start of the day, not at the end.)

/* NOTES on rebuilding parsedate.c (particularly for inclusion in CVS
|
||
releases):
|
||
|
||
We don't want to mess with all the portability hassles of alloca.
|
||
In particular, most (all?) versions of bison will use alloca in
|
||
their parser. If bison works on your system (e.g. it should work
|
||
with gcc), then go ahead and use it, but the more general solution
|
||
is to use byacc instead of bison, which should generate a portable
|
||
parser. I played with adding "#define alloca dont_use_alloca", to
|
||
give an error if the parser generator uses alloca (and thus detect
|
||
unportable parsedate.c's), but that seems to cause as many problems
|
||
as it solves. */
