Vladislav,
I really like your patch, but I have problem with '-' character.
Actually key name beginning with '-' is valid. So my proposed solution
is to:
- escape '-' character
- or (preferred) use some other character which is NOT valid key name.
It doesn't really matter for me, so which one do you prefer?
^?
*?
some other?
I was thinking about !,@,#,$,%,^,&,* ;). Actually, ^ seems to be closest
(* is also good, but one day we may decide to use it for regexp).

Function which checks key name validity:
static int icmap_is_valid_name_char(char c)
{
return ((c >= 'a' && c <= 'z') ||
(c >= 'A' && c <= 'Z') ||
(c >= '0' && c <= '9') ||
c == '.' || c == '_' || c == '-' || c == '/' || c == ':');
}
So basically ^[a-zA-Z0-9._-/:].

Honza
