I realize that this patch needs some introduction.
First, it is the logical follow-up of commit
c59e19cd774a9c5fb658a4b538ab505d608820a5
Author: Peter Stephenson <pws@users.sourceforge.net>
Date: Tue May 10 15:40:32 2011 +0000
29191 (Danek) and 29203 (with fixes): make TERMINFO variable special.
Second, there has been discussion on the mailing list about his before.
The general idea is that terminfo look for these varibales via getenv(),
To pass them correctly, we need to export them to our own environment.
The term update is just a nice extra feature avoiding the TERM=$TERM trick.
See discussion about this in [1]
Third, there has already been an update for this issue in fish[2].
Bash seems unaffected by this issue, but I have no idea why...
Finally, this arises from an issue in the nixpkgs tracker, at [3].
I am not aware of the review/accept policy for patches.
Could you tell me if this one has any chance to get merged ?

Guillaume Maudoux, aka layus.

Can't see any problem generally, given it's exactly parellel to the
TERMINFO trick.
Usually you just need to post it (without the "> " and by any mechanism
that doesn't cause line wrap or other modifications) and wait for people
to comment.
One issue is that the doc implies (and people would probably expect)
that TERMINFO_DIRS is a tied variable with a terminfo_dirs array
equivalent. This doesn't exist. This would need accessors along the
lines of the contents of colonarr_gsu for the colon-separated version
and vararray_gsu for the array version. Possibly only the setters are
different.

My initial mail contained only the patch, in the correct format.
I then send a description, scrambling the patch... Seems like I am
unable to get both right ;-).

Would it be okay to change only the docs ? There is no reason to make
TERMINFO_DIRS a tied variable.
It's a basic raw variable passed to ncurses, not a widely used variable
like $path.
I just copied the description of some array variable, trying to be smart...
I will submit the same patch with a better doc.
