[PATCH] i386: multi-column stack backtraces
Print stack backtraces in multiple columns, saving screen space. Number of columns is configurable and defaults to one so behavior is backwards-compatible. Also removes the brackets around addresses when printing more that one entry per line so they print as: <address> instead of: [<address>] This helps multiple entries fit better on one line. Original idea by Dave Jones, taken from x86_64.
