there should be two different options:
1. download by name
2. download by regex

You can disable regular expressions in your config file:
http://code.google.com/p/googlecl/wiki/ConfigurationOptions
I'd recommend expanding your usage of regular expressions, however, since this
is a major benefit of the command line. For example, to match exactly, you can
use "^name$" ("^" will match the beginning of the string, "$" matches the end
of the string)
The parenthesis and periods can be escaped with a backslash: "12\.13\.2004",
"new folder \(2\)"
There's a comprehensive list of expressions at
http://docs.python.org/library/re.html
I'll leave this issue up in case other people want a similar feature, but I
doubt enabling/disabling regex will be included on the command line.

Well. suppose this scenario:
1. download list of albums
2. download albums selected by user.
So in step 2 my script (BASH) should escape all regex-special-symbols. I think
it is wrong API.
Also, denial of service may be used when regex used in inappropriate places.:
$ egrep 'a{100000000,}'
egrep: Memory exhausted

That bash script would definitely benefit from a command line option to
enable/disable regex. But it's still not an option very useful for most users.
And if you really want to do a bash script, you could use sed to change the
setting in the configuration file:
PATH_TO_CONFIG = /my/config/file
sed 's/regex = True/regex = False/' $PATH_TO_CONFIG > $PATH_TO_CONFIG
As for the inappropriate regex, the user will only be able to slow down their
own machine -- regular expression matching is done after the query to the
server.
