The usage of "capture group (...)" in the immediate condition after `&&`
results in `$1` being uninitialized. This eventually crashes the script.
It does not really crash it, right? It just emits a warning.
Sir,
Yes. I will modify the line accordingly.
Fix this by placing the capture group in the condition before `&&`.
Thus, `$1` can be initialized to the text it matches thereby setting it
to the desired and required value.
Maybe you can look when this bug was introduced?
The bug was first introduced with the commit `e518e9a59ec3` when the block was
added to the script. It has been like that since then.
Should I add this detail too in the commit message?
