Mark symbol in "[the] command <symbol>" as callable

[kisaragi-hiu]

This, for example, skips an unnecessary "show variable?" for local minor mode variables.

Whereas recentf-mode (global) says:

Non-nil if Recentf mode is enabled.

See the recentf-mode command for a description of this minor mode.

, whitespace-mode (local) says:

Non-nil if Whitespace mode is enabled.

Use the command whitespace-mode to change this variable.

. This change catches the latter case.
