Subject: el/dot-emacs.el (mdw-misc-mode-config): Check for derived modes.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~mdw/git/profile/commitdiff_plain/1bb62621e6163703c18750516bfc1317f79924ab

el/dot-emacs.el (mdw-misc-mode-config): Check for derived modes.

When inspecting modes to decide what to do (e.g., overriding
keybindings), use `derived-mode-p' to check for derived modes as well as
just the exact modes of interest.
