Subject: (Fdisplay_buffer): If largest or LRU window is the
X-Git-Tag: archive/raspbian/1%29.2+1-2+rpi1~1^2~421^2~17865
X-Git-Url: https://dgit.raspbian.org/%22http:/www.example.com/cgi/%22https:/www.github.com/%22bookmarks:///%22http:/www.example.com/cgi/%22https:/www.github.com/%22bookmarks:/?a=commitdiff_plain;h=ed39f60cf7785a19db958139363e19e10dd1d304;p=emacs.git

(Fdisplay_buffer): If largest or LRU window is the
only window, split it even if it is not eligible for splitting.
This restores the original behavior broken by the 2007-07-15
change.
