Subject: [PATCH] bash: adjust example to read from file into array (#2187)

* use `$()` rather than deprecated ``
* illustrate shortcut for builtin read of file without `cat`
* don't imply this reads lines, it will split into words by default

perhaps the cheatsheet should have a section on IFS, but that's
off-topic for this patch.
