[9front] [PATCH] Make pstree work with proportional fonts

[Blue-Maned_Hawk <bluemanedhawk@gmail.com>]

Pstree's current placement of the box-drawing characters after an 
inconsistent proportion of digits and spaces means that they don't align 
when using proportional fonts.  This patch rearranges the output of 
pstree to have the box-drawing characters first.
