a7e1e4cc64 Add support for journalctl output 
The lines in the "Mem-Info:" block start with spaces instead of date /
time / hostname. As a result, removing the needless columns no longer
works correctly.

7038cced1f Fix finding line with "CPU:" 
The line is used to calculate the number of leading columns to remove.
Depending on the OOM version the pattern is on second or third oom line.

9a5dbbc255 Fix the order of processing #012/LF 
Remove unnecessary columns first and unwind #012 (octal replacement of
LF) second. Otherwise, important content would be lost.

41a51a7e2a Rework removal of unused information 
The columns left to the oom are not used. With this change, the
algorithm becomes more robust and can better handle known special
cases like "kernel:<processname>".

easier to change the name in a test case.

d964d657ba Allow all non-whitespace chars in program names 
Program names in Posix can contain all characters expect the null byte.
The code allows \S (all non-whitespaces) and spaces in program names.
This excluded some allowed characters like \n, \r and \t. No negative
effects should arise from this.

967d231be5 Use transcrypt --sform to enable string formatting 
The Python string formatting mini language isn't enabled by default.
"{}".format(42) works fine but "{0:x}.format(42)" returns "{0:x}"
instead of "2a" if the mini language isn't enabled.

Newer Red Hat 7 releases changes the output of the OOM a little bit. The
last output line "Killed process" contains the process UID now.

    anon-rss:20629004kB, file-rss:0kB, shmem-rss:0kB
