Ideally, it would be real nice to have an option that returns the coord
and value on a single line.

Looking at the news file, specifically about gdallocationinfo:
gdallocationinfo: avoid extra newline character in -valonly mode if
coordinate is outside raster extent (3.9.0 regression)
Having that new-line character is imperative. For instance, say I have a
file called coords.txt with the values:
-122.999312 37.341868
-122.999089 27.573119
-122.998763 18.92525
-122.998927 32.975703
Then I run the command:
gdallocationinfo -geoloc -valonly raster.tif < coords.txt > results.txt
...with results.txt:
0
767
327
The 3rd coordinate is outside the raster extent, it's empty or null. I
will still get 4 results, which is very important. If I now try to
append results.txt to coords.txt, I get a 1 to 1 relationship:
paste -d " " coords1.txt results.txt |tr " " ","
-122.999312,37.341868,0
-122.999089,27.573119,767
-122.998763,18.92525,
-122.998927,32.975703,327
The problem is, if that newline is removed, results.txt will have 1 less
line than coords.txt. This is bad.
Thanks for listening!
