Arkadiusz Drabczyk b260aaeca9 proc.5: Inform that comm in /proc/pid/{stat,status} might also be truncated 
pgrep for example searches for a process name in /proc/pid/status
and therefore cannot find processes whose names are longer than 15
characters unless -f is specified.

Michael Kerrisk bad1c6c80c tzfile.5: Explain UT abbreviation 
From a conversation with Paul Eggert:

From: Paul Eggert <eggert@cs.ucla.edu>
Subject: Re: Errors in man pages, here: tzfile(5): Typo?

On 4/20/20 12:27 AM, Michael Kerrisk (man-pages) wrote:
> I think "UT" here is intended to mean "Universal Time", and as such

Yes, that's right. The tzfile format covers timestamps that predate the
introduction of UTC in 1960, so the documentation uses the sloppier and
more-general term "UT" instead of the more-precise term "UTC".
