hub: Avoid possible vim-isms when vi(1) is used

If the editor used matches the `\b(?:[gm]?vim|vi)(?:\.exe)?$' regular
expression hub automatically add as arguments `--cmd'. The `--cmd' passed is
probably supported only by vim so delete the `|vi' from the RE in order to not
append possible non-standard arguments to non-vim vi-s.

(This was spotted using `hub pull-request' that failed due non supported
argument passed to vi)
