Rename hist command to something less likely to be a shell builtin #54

My shell (ksh93) informs me that

$ type -a hist
hist is a shell builtin
hist is /Library/Frameworks/Python.framework/Versions/3.6/bin/hist
hist is an undefined function

in other words, if I try to run hist I will get the shell builtin first. I can circumvent that by using the env program, but this is not obvious right away.
