[PATCH 1/3] build.py: minor shell_trap_code() formatting tweaks

[Andre McCurdy <armccurdy@gmail.com>]

Fix quoting of $BASH_COMMAND and avoid wrapping at 80 columns (the
script which follows is likely to contain some very long lines, so
line wrapping in bb_exit_handler() looks somewhat out of place).
