Subject: emacs: improve compat for (version< "27" emacs-version0
X-Git-Url: https://git.shemshak.org/gitweb.cgi/~bandali/configs/commitdiff_plain/946188e1d6c6ba713f3d34a25c21b395234b043f

emacs: improve compat for (version< "27" emacs-version0

- eshell: it seems that eshell-hist-mode-map is new in 27
- mm-uu: :extend is new in 27. trying to use it pre 27 causes severe
  breakage of ERC among other things
