Well, you raise a valid point as to the commands not being logged. 
Again I would prefer simplicity, so just install a keylogger. There
is no need to overcomplicate things. Though a keylogger will not work 
on most *nix systems to my knowledge. Though all of this should be 
negotiated with the client prior to the pen test being done ie: what 
kinds of logs will be retained and the such. This is one thing which 
should be spelt out clearly prior to any pen test actually taking place.

The simplest solution would be to simply log all activity using tcpdump in binary 
format. This decreases the file size, is faster, and allows you to manipulate it after. 
You can also input this binary log into any protocol analyzer afterwards as well ie: 
ethereal, etherpeek nx and the such. 

Doing the above also gives you and your client a copy of exactly what it is you have 
done during your pen test should there be any questions/complaints.

Which s great on the data being obtained, yyet fails to retain the nature
of the exact command that retrieved the data, so make sure one either
tee's allcommands to a file <date stamps can help here> or one runs script
or something.  This helps if one has data results that are similiar and
they need to know which command applies to which data, as well as make it
possible to dupe scenarios.
