Hello,
with MacVim, the "macmeta" currently allows to use both "Option" keys
either as "Meta" or "AltGr". Like a lot of European users, I'd prefer
the "macmeta" pref to set only one "Option" key as "Meta" (e.g. the
left one, as it works on Windows and GNU/Linux) and keep the other one
for special characters on non-English keyboard layouts.
In case someone is interested if having both a Meta key *and* an
Option key when "macmeta" is set, here's a quick and dirty patch:

This is just a trivial adaptation of this iTerm patch:

I think a proper MacVim integration would require to modify the
'macmeta' stuff, e.g. by using a string pref instead of a boolean one:
* set macmeta=l => left Option key is Meta
* set macmeta=r => right Option key is Meta
* set macmeta=rl => both Option keys are Meta
* set macmeta= => no Meta key
Thoughts?
Cheers,
