Subject: Makefile: Only set up `bracketed-paste' on Emacs 24.3 or later.
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~mdw/git/profile/commitdiff_plain/486623cb8d2a0c229b36a81f6fc03ef9e093ae93

Makefile: Only set up `bracketed-paste' on Emacs 24.3 or later.

It depends on `cl-macs', which only became its own proper library in
24.2.90.  The tricky part was the new machinery to discover the Emacs
version in detail.
