Summary and Info:
pacman shouldn't contain any special terminal logic or whatever else it is that causes different stdout behaviour, whether the endpoint is an interactive terminal or a pipe.

Steps to Reproduce:
Compare 'pacman -Si (or -Qi) syslog-ng' to 'pacman -Si syslog-ng | grep Description'.

That doesn't make any sense. How would we scale progress bars otherwise? It has to contain some terminal logic otherwise interactive output is impossible.

The issue you really wanted to address appears to be line wrapping in --info output, which is a legitimate gripe. Note that normally we do some indented printing, so this is not as cut-and-dry as it may appear.

In previous versions, when there was no tty, we did not output the progress bar at all.

Is this an issue anymore? There is no example output so I can not compare, but "pacman -Si syslog-ng | grep Description" looks fine to me now...

Oh, totally forgot about this one.
Seems like it's solved, I used foomatic-db-engine with its long description and glibc (Required by) for testing.
