Bug #3034: Tail -n 1 don't work on /proc/curproc/map

* Author: cpk
* Status: Resolved
* Priority: Normal
* Assignee: 
* Category: VFS subsystem
* Target version: 
If i run tail -n 1 /proc/curproc/map it will print 10 last lines.(wc says it is 11 but something is wrong here)
But then if i redirect output to file and then tail it it will print correct number of lines.

tail -n 1 /proc/curproc/map |wc -l 
    11     143    1111
tail -n 1 /proc/curproc/map > /tmp/tail-bug && tail -n 1 /tmp/tail-bug |wc 
    1      13      95
