All this shows why this one is 5/5 and separate ;) I was thinking hard
about the best display also. From my point of view, there are two
arguments against the seemingly more user friendly variants (collapsing
fetch and push entries with the same url):
- It introduces 3 different types of lines, rather than 2.
- The code would have to go through all (push) urls and check whether it
matches url[0].
While the latter one is technical, the first makes it more difficult to
parse the output, both visually and programmatically (I know, porc...).
Note that at least implicitely we always had 2 different types of lines
in the output of "remote -v": the first one (fetch+push) and the others
(push). There is no way to keep only those 2 types (when there is a
"pushurl" setting), my suggestion was to use 2 types now for the 2 purposes.

I thought it's complicated enough for the little change in output... But
what do strbufs bring us here?
Before the patch, builtin-remote would leak the string_list. They way I
use malloc enables me to free the string list (using string_list_clear)
later on, including the strings and utils. strcpy and strcat look a bit
low level but I see no point in using the sprintf shotgun here.
More or less I have zero clue about strbuf (OK, probably not less...)
but I think that if util is a strbuf then freeing everything would be
more complicated because a strbuf may or may not be allocated.
