Subject: 	* tests/canvText.test: 	* win/tkWinFont.c (Tk_MeasureChars):
 Fix for text 	wrapping problem that appeared using canvas text 	under
 Win32. A long wrapping string that had 	leading spaces was being
 incorrectly wrapped. 	This change makes the Win32 implementation behave 
 the same as the Unix implementation. [Patch 1006286]
