Note: This is only done on startup. If the xterm options are changed after
Vim has started, the escape sequences may not be recognized anymore.
+ *xterm-true-color*
+Vim supports using true colors in the terminal (taken from |highlight-guifg|
+and |highlight-guibg|), given that terminal supports this. To make this
+work, 'guicolors' option needs to be set.
+
+Sometimes setting 'guicolors' is not enough and one has to set the |t_8f| and
+|t_8b| options explicitly. Default values of these options are
+`^[[38;2;%lu;%lu;%lum` and `^[[48;2;%lu;%lu;%lum` (replace `^[` with real
+escape) respectively, but it is only set when `$TERM` is `xterm`. Some
+terminals accept the same sequences, but with all semicolons replaced by
+colons (this is actually more compatible, but less widely supported). These
+options contain printf strings, with |printf()| (actually, its C equivalent
+hence `l` modifier) invoked with the t_ option value and three unsigned long
+integers that may have any value between 0 and 255 (inclusive) representing
+red, green and blue colors respectively.

*xterm-resize*
Window resizing with xterm only works if the allowWindowOps resource is
enabled. On some systems and versions of xterm it's disabled by default
