Now-closed duplicate #33386 reported that μ, 0x3bc, is not selected as part of
identifiers when double clicking. This prompted some research.
The 'Windows' style imitates the behavior of Command Prompt, which I presume is
a carryover from DOS days. PowerShell stuck with it, but Notepad, Notepad++,
Microsoft Word, Firefox, Thunderbird, and ??? have not. I think Tcl should have
switched long ago. In any case, I will go with whatever the tcl re engine
defines as word chars, the 'Motif' style', rather than attempt to write a giant
re, which would have to change as characters are added.
Do we still need this line in fixwordbreaks?
tk.call('tcl_wordBreakAfter', 'a b', 0) # make sure word.tcl is loaded
I will leave it until you say we don't.
After patching, 'abcμμμdef' ('0x3bc'*3) is selected as one word instead of
word, nonword, word. 'abc+efg' is still selected in 3 pieces, instead of the 1
word seen by Command Prompt.
