* tests/text.test: Added tests for -regexp -nocase searches with

backslash character classes.

* generic/tkText.c (TextSearchCmd): Text search did not work
properly when -regexp and -nocase were used, in combination with
backslash character classes represented by capital letters (ie,
\W, \M); altered implementation of -regexp -nocase searches to use
new regexp interfaces to fix this problem.  [Bug: 5988].
