This patch fixes the problem I described here:
https://groups.google.com/forum/#!topic/vim_dev/8bXZRbsj5Tc
When a character is found after <Esc> is pressed in insert mode, the buffer
length is incremented, but the typebuf.tb_noremap flag isn't set, so it uses
whatever was in there already. That's why the problem was intermittent.
Disabling that special case 'if' statement worked because it removed the call
to incar(). Setting notimeout and nottimeout worked because it specifically
checks for that in the 'if' statement.
This also fixes other key codes in insert mode. I had disabled the vitality
plugin (which makes focus autocommands work in a terminal) when running Cygwin
because half the time it would insert literally <F24> or <F25> instead of doing
the mapping (vitality maps to those keys as hooks for the autocommands). It
turns out that was caused by the same bug.
Very simple fix, but it was really challenging to find the cause.
