Bug in :set-termcap

[Matt Wozniski]

At :help :set-termcap, an example shows the command

:set <M-b>=^[b

This command does not work as expected when 'encoding' is set to
something multibyte. The reason seems to be that vim recognizes the
input bytes 0x1B 0x62 as a metafied 'b', and then stuffs 0xE2 into its
internal text buffers - a byte which is not reasonable unicode. As a
result, vim continues waiting for more bytes to finish the
(unintentional) sequence, until it gives up, decides that the sequence
is invalid multibyte, and just returns the first byte as a character.
The attached patch fixes this by stuffing the multibyte bytes
corresponding to the given codepoint into the input buffer instead.
I'm not sure if there's a better way to handle changing the size of
MAX_KEY_CODE_LEN in src/keymap.h, but Bram will know for sure.

Thanks for the patch. This stuff is a bit complicated, it does looks
like your solution is the right one.
