Internally, we represent `git config`'s type specifiers as a bitset
using OPT_BIT. 'bool' is 1<<0, 'int' is 1<<1, and so on. This technique
allows for the representation of multiple type specifiers in the `int
types` field, but this multi-representation is left unused.
In fact, `git config` will not accept multiple type specifiers at a
time, as indicated by:
$ git config --int --bool some.section
error: only one type at a time.
This patch uses `OPT_SET_INT` to prefer the _last_ mentioned type
specifier, so that the above command would instead be valid, and a
synonym of:
$ git config --bool some.section
This change is motivated by two urges: (1) it does not make sense to
represent a singular type specifier internally as a bitset, only to
complain when there are multiple bits in the set. `OPT_SET_INT` is more
well-suited to this task than `OPT_BIT` is. (2) a future patch will
introduce `--type=<type>`, and we would like not to complain in the
following situation:
$ git config --int --type=int
