Dear grep maintainers,
I think I've found a file that makes grep display wrong things, namely
endlines when grep is run "alone", piping just two greps together vs. text
when the output is piped e.g. to more or hd (hexdump).
You can find this file attached, but the file is public and can be found in
this zipfile:
https://www-intuidoc.irisa.fr/files/2017/07/ComplementaryInfo_LMDHG.zip
(part of the Leap Motion Dynamic Hand Gesture (LMDHG) database:
https://www-intuidoc.irisa.fr/en/english-leap-motion-dynamic-hand-gesture-lmdhg-database/
).
The offending command is this one:
#> grep -v "Position\|hand type\|^\t\t$" ArticulationsOrder.txt | grep
'[^A-Z]' # outputs just endlines
While:
#> grep -v "Position\|hand type\|^\t\t$" ArticulationsOrder.txt | grep
'[^A-Z]' | more # outputs this lines

I can reproduce this also on my Raspberry Pi 4 (with Ubuntu 18.04 and grep
v3.1 as well) and another x86_64 node with Xeon Silver belonging to a
research cluster (grep v2.20).
If you have any questions, do not hesitate to contact me. Thanks for all
the work you do.
Best regards
Andrea Ranieri
