file copy will copy directories. And with my change, that can be  
shortened to just copy.

Docs on this can be found with `man n glob`. You may simply want to  
put in a reference to glob(n) there.

Nope. The syntax for reinplace is `reinplace pattern file1 [file2 ...]`.

If you want to make things simple, you can do something like

foreach pat [list pat1 pat2 pat3] { reinplace $pat file1 file2 }

If the pattern has spaces, be sure to enclose it in quotes or braces  
(just like you do with reinplace)

Incidentally, the pattern is a single command as understood by sed  
(in fact, it's actually interpreted by sed under the hood).

What do you mean by this?

Clarify 3 and I may be able to answer this as well.

Sounds good.
