+The TERM environment variable is set to 'dumb' when running tests, but\r
+the original value of it is stored for echoing colors and running emacs\r
+(somewhat interactively) in detached session. Emacs requires some\r
+terminal control sequences to be available for interactive operation.\r
+In case original TERM is (also) 'dumb' (or nonexistent) emacs cannot run\r
+interactively. To fix this problem dtach (and emacs as it's child\r
+process) is run with TERM=vt100 in case original TERM was nonexistent or\r
+dumb. This way there is a chance to run emacs tests with different user\r
+terminals and potentially find problems there.\r
