I think I found the reason for this behavior. Try to strace man with
closed std*[1], and you'll get this:
	open("/var/catman/index.bt", O_RDWR) = 2
and few lines after that:
	write(2, "\rUpdating index cache for path "..., 50) = 50

Possible answer: 2 is usually stderr, but unfortunately, not this
time.

Possible solution: test for std* on start of man, and reopen it.

Hope this helps.

[1] How to strace man with closed std*, strace -o f man >&- 2>&- is
not working as expected...
