[sf-perl] regex problem: append path only if not in list already

[yary]

I added a few more test cases
to pcre_regex_to_append_path_non_redundantly.t, all of which your edit
passes. Congrats! And thanks for the commented "/x" version. Indeed the
"\s*" parts are not needed, I was guessing that the directories had
optional whitespace around the separating colons. And maybe if I had
started the task with the commented-extended-regex syntax, I would have
caught the error!

Odd, I didn't keep the window I tried out my answers in, and there's
something in my memory that isn't in the solution I posted- I thought I
explicitly matched the "secure_path" part on the left, which the "real
world" use-case needs.

-y
