Subject: [PATCH 3/3] kdb: bl: don't use tab character in output

From: Randy Dunlap <rdunlap@...radead.org>

The "bl" (list breakpoints) command prints a '\t' (tab) character 
in its output, but on a console (video device), that just prints
some odd graphics character. Instead of printing a tab character,
just align the output with spaces.
