Greetings,

interesting...
I wonder whether this is by design or by accident?

Looking back at my original example, another thing is appears to be non-obvious. The (backslashed) portion that reads:

\\\\\+\\\- # matches literal \+\- in a variable
[download]

had originally been written as:

\\\+\\\- # matches literal \+\- in a literal regex
[download]

why do I need an additional '\' before a quoted + and only within a variable is beyond me.... Same reason?
Cheers,
alf
