Review comment:
Yes. It was not needed.
In fact if you want the full story - that was a bit of a hack to have
non-empty parameter list. The problem is that in the version of bash that is
popular (and used in Travis/Dockerhub) an empty bash ARRAY is treated as
undefined variable (only in latest versions it is not). I prefer to keep `set
-u` but it causes an empty array to fail when used. Therefore I added a flag
"-t" originally that I knew was irrelevant (allocating terminal in this case
does not change anything - colors work, no user input needed). After adding
"-e" the array was not empty and I could remove "-t"
