[mosh-devel] Mosh fixes

[Keith Winstein]

Thanks Christine.

If the lambdas are this big of an obstacle, I guess I will just
rewrite them in less adventurous C++. It's not worth the hassle and
there's only like 10 of them anyway.

Once I get that done and the man pages (which should be a couple
days), I will ping you again about uploading to Debian.

Thanks again,
Keith
