commands: Fix off-by-one shift in setinpath/regex

Rather than complicating the matter by adding 1 to shift the specific
set command (not sure why this works for me in testing, since
`parse_setting_from_line` already drops the command) and then taking the
minimum of the length of the path and 1 because of the "path=" bit
that's always present, even if the path is an empty string, we just
recreate the argument, substituting "=" for "path=", and iterate over
the whitespace seperated parts and shift once for each.
