Set IFS env variable to "" for overlay_text shell expansion This prevents wordexp function from splitting the output of shell expansion into “words” and, as a consequence, removing the newlines from it. With this commit applied, setting overlay_text = $(echo -e 'hello\nworld!') displays hello world! in Imv window. Without this commit, the same overlay_text setting would display hello world! since wordexp splits the string "hello\nworld!" into two words and connects them with a space. This should not break any of the commands executed in $(), because the IFS variable is *not* inherited by their shell. The commands don't see this change and run with the default IFS value.
