Bug fix for script parsing

[nstrayer]

Add clarifying comments and structure to the script/ dependency parsing helper function

[hbaniecki]

Thank you @nstrayer!! This single line, the lack of any() in the CRAN release, breaks my package on devel environments due to a new warning in R 4.2. https://cran.r-project.org/web/checks/check_results_modelStudio.html

Please, would it be possible to submit v0.2.6 of the package to CRAN as fast as possible?

Thanks in advance.
