Comment (by isaacdupree):

 getArgs never does wildcard expansion -- it's your shell (whichever one
 you use -- bash is common) that does it before invoking the process that
 you told it to invoke.

 (This is a common point of confusion, since it's the process's
 responsibility to deal with other things like command-line arguments.
 Bash's magic symbols to watch out for are, I believe,
 {{{
 globbing: ?*{}
 quoting: '"\
 interpolation: $`~
 pipes/multiple-commands: <>|&
 comments: #
 history (if enabled): !
 }}}

 It would be nontrivial for GHCi to copy globbing and quoting behavior, and
 impossible for it to mimic whatever-your-shell-is exactly (unless by
 invoking your shell as a subprocess. Which wouldn't really work for GHCi,
 which is meant to remain within a single ghc-process.)
