Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
entire enclosed block.
We could also make this stuff only come out when getpid() != 1
and thus avoid the install case (where it really is just too verbose,
and people have complained), but this seems less messy and no one
complained when tzsetup didn't print the final "things went fine!"
messages (which sort of contravene the UNIX spirit of only yelling
when you need to anyway).
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
- It no longer attempts to fiddle wall-vs-UTC-in-RTC. The results
were just confusing most of the time.
- The program no longer contains a pre-compiled list of timezones
(compiled by groveling through the tzdata source files for comments
starting with `ZONE-DESCR'). Now it uses the new `zone.tab' file
supplied with current versions of the timezone data files, to determine
the list at run time. (It also requires the ISO 3166 table I
committed some months ago.)
AS A RESULT, this program will NOT work until the new timezone data files
are committed (should happen sometime soon).
"." means the object directory, so it is just confusing to use it
when nothing is included from the object directory unless the object
directory is also the source directory. It is confusing for "."
not to mean the source directory anyway, so used `-I.'s should be
replaced by `-I${.OBJDIR}'.
. Replace my NIH-suffering code to detect the number of lines on
the terminal by the curses variable LINES.
. Fix the selection code for countries with more than one screenful
of locations. The very few people living in America/US/Pacific
now won't be charged for Indiana any longer... :)
. Removed the gross code that copied over the timezone file to
/etc/localtime, and create a symlink now instead.
