Regarding not thinking of them as acronyms: yeah I get that. I was wondering how to best phrase that sentence because, indeed, curl also does not stand for C Uniform Resource Locator in my head, or grep for global regular expression perl-style (if I'm remembering that one correctly). It's just curl and grep. However, whereas curl and grep are really treated as names, spps I can currently regurgitate only by thinking of stop-process, and I imagine most such abbreviations will be like that for a while.
