So they write `help computing` instead of `help to compute`

Here are examples

No source file or test is named. Start by searching the repository for existing grammar rules and tests covering verb forms, then use the issue’s examples and linked searches as inputs. Done means the checker flags “help computing,” “help getting,” “help searching,” and “help buying” as forms that should use “help to verb.”
