xenocara/app/xterm/xterm.h
martijn ff43a88e32 Make xterm use my_wcwidth unconditionally again. 
CharWidth is a conditional wrapper that assumes that all wide characters
in the range 32-126 and 160-255) are latin-1 characters and are identical
with the unicode (UTF-8) codepoints and result in a width of 1.

This is correct in so far that the names of these code-points are
identical, but for SHY (soft-hyphen) the explanation of how it should be
used differs between unicode and latin-1. Latin-1 assumes that it's always
displayed, for unicode it should only be displayed after local grammar
rules apply.

This wrapper got introduced in xterm #334 and is on the short-list of Thomas
Dickey to fix. Since we don't know when the next release is going to be,
commit this one now, so we have it fixed before 7.0.

Originally discrepency between xterm and wcwidth(3) pointed out by Lauri
Tirkkonen (lauri <at> hacktheplanet <dot> fi).
