RE: question about `sit-for' and `C-g'

[Drew Adams]

Let me just add that the doc of none of the functions I mentioned, whether Lisp
or C, mentions anything about handling quitting, the quit character, or C-g.

So if, as it appears to me, C function `read_char' handles C-g directly, this is
not documented for that function nor for any of the multiple functions that call
it, directly or indirectly.  This doesn't seem right.
