+Subject: [PATCH] Add shortcut to spawn new terminal in the current dir
+
+Build on bakkeby's doule fork version. Use /proc/self/exe as the binary,
+and argv[0] as the called name. This allows to have several different
+st's and running from build tree etc. Also skip the unnecessary readlink
+part, shell shall do that anyway. Futher mark the pty master as cloexec,
+so the fd's are not leaked to spawned processes.

+
+*"Inspired by the beauty of the arctic, the colors reflect the cold, yet
+harmonious world of ice and the colorfulness of the Aurora Borealis."* -
+[Nord Theme](https://www.nordtheme.com/)
+
+The default behaviour of st is to reverse the fore- and background
+colors of each selected cell. If you don't want the selection-colors to
+be reveresed but instead have fixed fore- and background colors apply on
+top of this patch the [selectioncolors](../selectioncolors/)-patch. Then
+set the following settings in your config.h:

+Subject: [PATCH] support w3m images
+
+w3m images are a hack which renders on top of the terminal's drawable,
+which didn't work in st because when using double buffering, the front
+buffer (on which w3m draws its images) is ignored, and st draws only
+on the back buffer, which is then copied to the front buffer.
+
+There's a patch to make it work at the FAQ already, but that patch
+canceles double-buffering, which can have negative side effects on
+some cases such as flickering.
+
+This patch achieves the same goal but instead of canceling the double
+buffer it first copies the front buffer to the back buffer.
+
+This has the same issues as the FAQ patch in that the cursor line is
+deleted at the image (because st renders always full lines), but
+otherwise it's simpler and does keeps double buffering.
