git-gui: use wordprocessor tab style to ensure tabs work as expected

patthoyts · patthoyts · commit c74408696497 · 2010-10-27T23:37:31.000+01:00
The Tk text widget tab style is tabular where the first tab will align to
the first tabstop and if that position is left of the current location
then just a single character space is used. With the wordprocessor style
a tab moves the next character position to the next rightmost tabstop
as expected for viewing code.
