Update README.md
Enhance WhitespaceAroundCheck

Enhance WhitespaceAroundCheck to check DO_WHILE and LITERAL_SWITCH
tokens.
Fix style of existing code.

Fix style for the enhancement to pass “mvn verify.”
Use a thread-safe map implementation to keep the compiled patterns.
Note that the comment about Pattern itself not being thread-safe was
wrong, only the Matcher instances created from a Pattern are not
thread-safe, but that's in the responsibility of the caller.
