Before trying to apply directory renames to paths within the given directories, we want to make sure that there aren't conflicts at the file level either. If there aren't any, then get the new name from any directory renames.

This is quite a low level function, so I wondered if we have such functionality
already, but neither string-list.h nor strbuf.h present a drop-in replacement.
Speaking of strbufs, this might be another "big thing" to use in this series as
strbufs make using strings (and its memory management) easier in git.
This functionality could look like this (in strbuf.c):
/*
* Adds all strings of a string list to the strbuf, separated by the
given separator.
* For example a list of ("a", "b") with sep=";" would result in "a;b" added
* to the strbuf.
*/
void strbuf_add_separated_string_list(struct strbuf *sb, struct
string_list *slist, const char *sep)
{
int add_sep = 0;
struct string_list_item *item;
for_each_string_list_item(item, s_list) {
if (add_sep)
strbuf_addstr(sb, sep);
strbuf_addstr(item->string);
add_sep = 1;
}
}

+ int i;

+ str += sprintf(str, "%s", slist->items[i].string);
+ if (i < slist->nr-1)style nit: blanks before and after '-';
+ str += sprintf(str, ", "); + } +}
