I thought it was a strange behaviour... I kind of found a workaround
but it also has problems:

Instead of using a list { } or two separate instances of curl, I
wrote the filename complete with -o and -z twice to download two
files with one instance of curl:
curl -R --user-agent tv.swedb.se.widget --compressed 'http://
tvguide.swedb.se/xmltv/svt1.svt.se_2006-04-20.xml.gz' -o ~/Library/
Xmltv/svt1.svt.se_2006-04-20.xml -z ~/Library/Xmltv/
svt1.svt.se_2006-04-20.xml 'http://tvguide.swedb.se/xmltv/
svt1.svt.se_2006-04-21.xml.gz' -o ~/Library/Xmltv/
svt1.svt.se_2006-04-21.xml -z ~/Library/Xmltv/svt1.svt.se_2006-04-21.xml

Doing it this way does respect the -z flag for both files since the
filenames are hard-coded.
But I need to do it for about 150 files... so I tried that too and it
seems that at least my version of curl does strange things when it
gets so many arguments.

I tried the 16 files I wanted for svt1.svt.se_YYYY-MM-DD.xml
(normally it's yesterday, today + 14 days) and while most of the
files respect -z and does not get downloaded if the dates on the
harddrive and server match, some do. It's not random either, if I run
the command twice, the same files get downloaded over and over again,
despite -z.

Below is the 16 files I want to check to see if they have been
updated. Currently only file 0,1,7,9 and 13 - 16 respect their -z
flags, the rest always gets downloaded. If I check one of them (for
example file 2) with a single curl call, then nothing is transferred
because of -z.

Yesterday when I tested 150 files with one call, most acctually
respected the -z flag but some didn't. But today it's not the same
files that get -z flagged as it was yesterday although repeated
invocations of curl today skips the same files, 0,1,7,9,13-16 so the
behaviour is static. Yesterday it also were certain files that never
respected -z despite running the command over and over again.

I do admit that I'm not going to do it this way but there might be
others that need to download several files with different names that
can't be calculated from a list and in theory this way is a "proper"
way to do it that *should* work, right?

The 16 files:
