Adds a command line switch to allow the user to specify the location
of the disk cache, rather than in the profile directory. The command
line switch overrides the cache location regardless the chosen
profile.
The changed code ignores the value of the command line switch if it
is not usable for this purpose.
In this implementation, the supplied directory name must should not
contain spaces.

I have uploaded a new change set, hopefully a little closer to acceptance.
Please give it a thought :)

Please take a look at http://dev.chromium.org/developers/contributing-code

In particular, the part about the user agreement and adding yourself to the
AUTHORS file.

File chrome/browser/profile.cc (right):

Line 535: // Override the cache location if specified by the user.
nit: Insert an empty line before this one.

Updated.
I was expecting one in the committing team to add a new name when necessary,
since I can hardly see this minute change as a "contribution" to the project :)
Anyway, I've added my name (I signed the user agreement before starting the work
since I expect to leave a wee bit bigger footprint in the code than just this
change ;)).
