A couple more script tweaks for clarity
- Because the substitition string after the hyphen is empty, "${VIRTUAL_ENV:-}" and "${VIRTUAL_ENV-}" have the same effect. However, the latter, which this changes it to, expresses the correct idea that the special case being handled is when the variable is unset: in this case, we expand an empty field rather than triggering an error due to set -u. When the variable is set but empty, it already expands to the substitution value, and including that in the special case with ":" is thus misleading.- Continuing in the vein ofd18d90a (and1e0b3f9), this removes another explicit newline by adding another echo command to print the leading blank line before the table.1 parentc7cdaf4 commitf6dbba2
