Subject: [screen-devel] [PATCH 1/1] Increase max TERM length to 40 characters
Date: Tue, 5 Apr 2011 03:26:58 +0000
Source: https://lists.gnu.org/archive/html/screen-devel/2011-04/msg00002.html

Some terms contain rather long TERM names these days, for example,
`rxvt-unicode-256color'. Increasing the max size for the TERM variables
avoids the `$TERM too long - sorry.' error when using these terms.
