An in-line Python script, while flexible, is arguably more complex and less stable than the long-lived `grep`, `awk`, and `printf`. Make use of these simple tools to display a column-aligned table of target and description help output. Also, the first target that appears in a Makefile is considered the default (when no target is specified on the command-line). However, despite it's name, the `default` target was not listed first. Fix this, and redefine "default" target to "all" as intended, instead of "help". Lastly, add a small workaround for a vim syntax-hilighting bug. Signed-off-by: Chris Evich <cevich@redhat.com>
