Module Name: src
Committed By: mlelstv

Modified Files:
src/lib/libc/gen: utmpx.c
Log Message:
strvisx is used here to encode binary data, but the encoding
depends on locale settings and the result might not be accepted
or even misinterpreted by the strunvis decoder. As a workaround
encode manually as a string of octal numbers.
strvisx should learn how enforce such an encoding by itself.
