Details:

I use gvim as an external editor.  When using the Octave GUI I can configure
an external editor in the settings.  The command to execute substitutes '%f'
for the file name and '%l' for the line number.  However, when Octave doesn't
supply a line number the result is that %l expands to -1 which is not a valid
line number.

I think in cases where the line number is not used %l should expand to 1 so
that the editor is opened at the beginning of the file.

For reference, the external editor command I used was


gvim %f +%l


and the Octave command was


edit ls.m
