William Chargin baecf2ce9e docs: --indent value has maximum of 7, not 8 ...

Test Plan:
To verify that this is in fact the behavior:

```
$ jq --indent 7 -n '[1]'
[
       1
]
$ jq --indent 8 -n '[1]'
jq: --indent takes a number between -1 and 7
Use jq --help for help with command-line options,
or see the jq manpage, or online docs  at https://stedolan.github.io/jq
```

This patch was generated by running `git grep "no more than"` and fixing
up appropriate results.
