Hi,

I use company-auctex for completion of latex symbols and I noticed that
while \Longrightarrow \Longleftrightarrow are completed, \imples and
\iff are not completed. I checked company-auctex's source and I believe
it ultimately gets these completions from the LaTeX-math-default
symbol defined in latex.el. I was hoping that \implies and \iff could be
added to LaTeX-math-default so that it would be possible to get these as
possible canidates for completion.

Thanks!
