Patch 7.3.1179
Problem: When a global mapping starts with the same characters as a
buffer-local mapping Vim waits for a character to be typed to find
out whether the global mapping is to be used. (Andy Wokula)
Solution: Use the local mapping without waiting. (Michael Henry)

Remove ALL mappings for the modes where the map
command applies. {not in Vi}

Warning: This also removes the default mappings.

Local mappings are also cleared when a buffer is deleted, but not when it is
unloaded. Just like local option values.

+ *map-precedence*
+ Buffer-local mappings (defined using |:map-<buffer>|) take precedence over
+ global mappings. When a buffer-local mapping is the same as a global mapping,
+ Vim will use the buffer-local mapping. In addition, Vim will use a complete
+ buffer-local mapping immediately, even if a longer global mapping has the
+ buffer-local mapping as a prefix. For example, given the following two
+ mappings: >
+ :map <buffer> \a :echo "Local \a"<CR>
+ :map \abc :echo "Global \abc"<CR>
+ The buffer-local mapping \a will be used immediately. Vim will not wait for
+ more characters to see if the user might be typing \abc.

There are situations where key codes might not be recognized:
- Vim can only read part of the key code. Mostly this is only the first
