Documentation/git-gc: improve description of --auto

This patch tries to make the description of --auto a little
more clear for new users, especially those referred by the
"git-gc --auto" notification message.

It also cleans up some grammatical errors and typos in the
original description, as well as rewording for clarity.

--auto::
With this option, `git gc` checks if there are too many
loose objects in the repository and runs
gitlink:git-repack[1] with `-d -l` option to pack them.
The threshold for loose objects is set with `gc.auto` configuration
variable, and can be disabled by setting it to 0. Some
Porcelain commands use this after they perform operation
that could create many loose objects automatically.
Additionally, when there are too many packs are present,
they are consolidated into one larger pack by running
the `git-repack` command with `-A` option. The
threshold for number of packs is set with
`gc.autopacklimit` configuration variable.
With this option, `git gc` checks whether any housekeeping is
required; if not, it exits without performing any work.
Some git commands run `git gc --auto` after performing
operations that could create many loose objects.
+
Housekeeping is required if there are too many loose objects or
too many packs in the repository. If the number of loose objects
exceeds the value of the `gc.auto` configuration variable, then
all loose objects are combined into a single pack using
`git-repack -d -l`. Setting the value of `gc.auto` to 0
disables automatic packing of loose objects.
+
If the number of packs exceeds the value of `gc.autopacklimit`,
then existing packs (except those marked with a `.keep` file)
are consolidated into a single pack by using the `-A` option of
`git-repack`. Setting `gc.autopacklimit` to 0 disables
automatic consolidation of packs.
