LogFormatUtils class abstract final

Formats values for log lines: what the framework writes about values from outside (a path, a user name, a header) goes through it.

A value from a client can hold line breaks and terminal escapes: logged as it is, ada\nINFO ... root logged in would add a forged line to the log, and an escape code would change what a terminal shows. formatValue replaces them, and cuts long values.

Spring (Java): org.springframework.core.log.LogFormatUtils.
