EDITOR varable unset by default causing error in settitle()

[ardentperf]

the scripts here do not set EDITOR variable but assume that it is set elsewhere. however this is not the case by default at least with a clean ubuntu 22.04 install. when EDITOR variable is unset, settitle() function begins throwing error "basename: invalid option"

could either have settitle() understand empty EDITOR variable, or could assign a default when it's unset

I have applied the change to force the creation of HOME_GIT for an initial .bashrc read, adding quotes around it to avoid surprises. Still need to look at the second one.
