keymap: Do not use vim_isIDc in keymap.c

Browse Source 
Note: there are three changes to ascii_isident. Reverting first two (in 
find_special_key and first in get_special_key_code) normally fails the new test 
with empty &isident, but reverting the third does not. Hence adding `>` to 
&isident.

Ref vim/vim#2389.
