[es-mx] Remove Spanish (Mexico) translation

This translation was copied verbatim from en in 02f9838 (as the
398db5e blob, which was added by b26a581).  All subsequent changes
have been tree-wide, so we don't lose any information by removing the
translation.  Future translators should seed their efforts with an
up-to-date branch from another language.
Mention --oneline in Table 2-2

`--pretty=oneline` is useful for explaining `--pretty`, but
`--oneline` is easier to type and its output is easier to read.
Add backticks around `git fetch pb` in section 2.5.

Following the example of the preceding `git remote add`.
