For example, I was unsure whether to default to 'emacs' or 'emacsclient'; the problem with the latter is that sometimes it's invisible, when the buffer pops up in some emacs far far away or maybe pretty inaccessible (a forgotten Emacs in a screen session?), and I was also unsure whether emacsclient would do the right thing if no Emacs was running.

Is this truly your biggest problem, it 'pretending to be more general than it really is'? Would it suffice to rename it to 'raiseXEditor' or something?

The infrastructure of getEditor and getBrowser is used at least 7 times in my config, although those two specific functions are only each called once.
