Error when creating a page with dot/period/fullstop in title

[qguv]

Creating a page with the title et. al. and any content causes the following error

Happstack 7.4.6.1

Something went wrong here
Internal server error
Everything has stopped

The error was "IllegalResourceName"

It's a bug in jgm/filestore's isInsideDir function. It just checks for .. inside the strings, rather than making sure that it's not something like et. al..page.

(And I just noticed that this is already mentioned in the comment above the function.)
