Subject: patch 9.2.0161: intro message disappears on startup in some terminals
X-Git-Tag: v9.2.0161^0
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=ef3d79ebbe014effa2acd15b26b42086f6c0eebf;p=thirdparty%2Fvim.git

patch 9.2.0161: intro message disappears on startup in some terminals

Problem:  intro message disappears on startup in some terminals
          (chdiza, after v9.2.0139)
Solution: Only call set_shellsize() in handle_csi() if the reported
          width or height actually differs from the current
          Rows or Columns. (Foxe Chen)

fixes:  #19656
closes: #19660
