typo

[Alexander Oblovatniy]

Hello,

There are couple of typos at page 4.9
Shells<http://www.freebsd.org/doc/handbook/shells.html>
.

Both foobar and foo.bar start with fo. By typing ., then pressing *Tab* again,
> the shell is able to fill in the rest of the filename.


Both 'foobar' and 'foo.bar' start with 'foo' instead of 'fo'.

Table 4.3 provides a list of common environment variables and their
> meanings.


Actual table's name is 4.4.

Thanks!
