Possibly bad path grammar

[ocket8888]

Python v3.6.7
Sphinx v1.8.5
sphinx_js v2.7.1
typedoc v0.14.2 (using Typescript v3.2.4)

I ran into an error where parsimonious threw an exception trying to deal with some path (stack trace just named it as ../../../docs/app/ap) but by adding my own print statement in doclets.py I was able to find out it seemed to be having trouble with parsing files with . in the name. Here's the output with that path print included:

sphinx-build -b html -d build/doctrees   source build/html
Running Sphinx v1.8.5
WARNING: The config value `js_source_path' has type `list', defaults to `str'.

The full traceback has been saved in /tmp/sphinx-err-v8cgfoxe.log, if you want to report the issue to the developers.
Please also report this if it was a user error, so that a better error message can be provided next time.
