Update remove-unneeded-files sol'n 4 in lesson 4 (issue #1415)

[sdrobert]

This PR is follows up issue #1415.

In the removing-unneeded-files question of lesson 4, the description of the 4th solution

The shell would expand `*.*` to match all files with any extension, so this command would delete all files

has been replaced with

The shell expands `*.*` to match all filenames containing at least one `.`, including the processed files (`.txt`) *and* raw files (`.dat`)

Note that the replacement text is slightly different from that suggested in #1415. I can easily use that text if the maintainers would prefer.

Best, Sean
