is2511 [Shell API] Tiny tiny fix `op` -> `ops`

   Returns values similar to `pcall` and `coroutine.resume`: the first returned value is a boolean indicating success or error. In case of errors, the second returned value is a detailed error message. Otherwise the remaining returned values are the values that were returned by the specified program when it terminated.
 - `shell.parse(...): table, table`
-  Utility methods intended for programs to parse their arguments. Will return two tables, the first one containing any "normal" parameters, the second containing "options". Options are indicated by a leading `-`, and all options must only be a single character, since multiple characters following a single `-` will be interpreted as multiple options. For example, if a program is called like this:

Options are indicated by a leading `-`, and all options must only be a single character, since multiple characters following a single `-` will be interpreted as multiple options. Options specified with 2 dashes are not split and can have multiple letters. Also, 2-dash options can be given values by using an equal sign. The following examples all assume the script `program` parses the options using `local args, ops = shell.parse(...)`.
-  `program -abC -d arg1 arg2`
-  And `program` does `local args, options = shell.parse(...)`, then `args` is the table `{"arg1", "arg2"}`, and `options` is the table `{a=true,b=true,C=true,d=true}`.
+  `program`
-- `shell.running([level: number]): string`
-  Deprecated, use [[api:process|process.running]].
+  # `args` is `{}`
+  # `ops` is `{}`.
+  `program -abC -d arg1 arg2`
+  # `args` is `{"arg1", "arg2"}`
+  # `ops` is `{a=true,b=true,C=true,d=true}`.
+  `program -abC --dog arg1 arg2`
+  # `args` is `{"arg1", "arg2"}`
+  # `ops` is `{a=true,b=true,C=true,dog=true}`.
+  `program -abC --dog=foo arg1 arg2`
+  # `args` is `{"arg1", "arg2"}`
+  # `ops` is `{a=true,b=true,C=true,dog="foo"}`.
+  On this next example, notice the single dash before `dog`, this causes all of the token to be parsed as single chars.
+  `program -abC -dog=foo arg1 arg2`
+  # `args` is `{"arg1", "arg2"}`
+  # `ops` is `{a=true,b=true,C=true,d=true,g=true,["="]=true,f=true,o=true}`.
