You are misusing backticks. The normal use is something like:
:e `glob(pattern)`
Vim can't really make a difference for what expression you use inside
the backticks. That would be too complicated.
If we want something to take the expression literally we would need
another mechanism. Perhaps a command modifier that disables wildcard
expansion, something like:
:nowild e file[a].txt
