I used the phrase "modernization" just because `file-append` is a 
g-expression-related procedure, and my understanding is that gexprs are 
the new way to do things. I hadn't considered the 
fixing-to-specific-packages aspect. In theory one could bind a 
replacement package to the same name in the scope of g-expression 
expansion (package parameterization, for example, will enable this more 
simply if and when it's done), but that's kind of hacky atm and 
shouldn't be a burden on anyone inheriting from this package. I now 
understand why one might prefer `search-input-file` and, furthermore, 
think it should be preserved.

If no one else has input on this in the next couple days, I'll try to 
remember to close this issue soon :)

Thanks for helping me think about something in a new way!
