Incorporate the diff from entrez describing the travel_debug wizard
mode option and removing obsolete M prefix from the Guidebook. That
missed a reference to it in the description of '_'.
I put M back in case someone who has used it with earlier versions
tries to use it and gets a no-such-command complaint so goes looking
for it.
Also, make the mention of ^X at the end of the discussion of status
stand out a bit. The indentation of its paragraph made it line up
with the preceding text instead of making it be distinct from that.
The TeX changes are untested and given the amount of punctuation
characters used, it will be surprising if they all have been quoted
properly.
