 Methods can be shortened to their closest unambiguous forms, e.g. a, d, or l.
 However, due to implementation specifics, any string starting with those forms
 will work; that functionality is unspecified and is not guaranteed.

-For example, the following are equivalent:
-    apkv add syslinux .virt
-    apkv a syslinux virt
-    apkv abcdefg syslinux .virt
+For example, the following are equivalent, with the first being preferred:
