[gentoo-portage-dev] [PROPOSAL] Don't split user visible messages across multiple lines

[Alexandru Elisei]

I was working on emerge --sync and my test repo configuration
generated several warning messages. Finding the exact location where
the warnings was generated was surprisingly difficult because the
message string was split across three lines due to the 80 character
line limit and I had to grep for different patterns until I found one
that matched part of a line.

I propose that messages that are visible to the user never be split
across multiple lines. This is also the coding style convention used
by the linux kernel:

If accepted, this could go in the DEVELOPING file.
