Use shell script highlighting where it is resonable, use console
highlighting for transcripts, and fix some of the few cases where the
syntax was broken, resulting in text not being rendered at all.

GXemul supports MIPS Malta but with some limitations.
The most notable problems:

  * PCI-enabled barebox just hangs under GXemul;
  * by default gxemul uses 5Kc processor,
    so we have to force MIPS32R1 processor usage.

To fix these problems the special gxemul-malta_defconfig
is introduced and the board's documentation is updated.
