The simple fix is to build a shell script front end to emacs that converts
the '+1' argument into a '-g1' argument and then execs the real emacs.  It
slows it down a little, but not that much.  Benefit is that you get less
interfaced to emacs just like it would be to vi.

The long fix is to check the linenumber code within less and convert the
sprintf function that builds the command that less will execute to start
up the editor (grep for 'system(' in the .c files).  Have it check the name
of the editor and construct the system() string appropriately.

Alternatively, you could modify the main() routine in microemacs to accept
a '+' argument as well as '-' arguments.  Not exactly straightforward, but
not too hard.

Recommend going with the first idea, even if you have to right a small program
to do it.  It's probably the quickest.
