Change the default behaviour which ignores folders with leading underscore

[75lb]

As part of an automated process, jsdoc-api writes source code to the system tmp folder (returned by os.tmpdir()) then parses it using jsdoc -X.

However, some users are reporting that jsdoc-api randomly fails with There are no input files to process yet a reboot of the machine fixes it.

It's because the system temp folder path occasionally features a leading underscore, e.g.

/var/folders/_9/nl_3vwh14lx9325r9cn6s08s96pd8g/T/

If there is a leading underscore in any part of the working directory tree, jsdoc fails. Could this default behaviour be reconsidered please? It leads to confusing, intermittent bugs.
