[PATCH] Texinfo: inconsistent behavior: cmd line vs. env

[Bogdan]

Hello.

 As suggested by Gavin, I'm reporting a problem (or at least a 
"surprising inconsistency") in the texi2dvi script. This is related to 
Automake bug#29188 (https://debbugs.gnu.org/cgi/bugreport.cgi?bug=29188).

 Since texinfo-4.9, one can set the build directory with an 
environment variable "TEXI2DVI_BUILD_DIRECTORY". Unfortunately, 
texinfo has a problem/inconsistency there. When setting "--build-dir=" 
on the command line, the build mode is set to "tidy" (which cleans 
some log files, etc.). Fine. The problem is that if you set the build 
directory using an environment variable, the mode is NOT set to 
"tidy", leaving the logs files (and failing tests in Automake). 
Luckily, you can also set the build mode from an environment variable, 
"TEXI2DVI_BUILD_MODE".

 The attached patch changes this behavior: when the user provides the 
build directory via an environment variable, but not the build mode, 
set the build mode to 'tidy', to match the command-line processing. I 
did a simple manual test, seems to be working.

 Thank you for Texinfo!

 P.S. I didn't manage to find any bugtracker for Texinfo, so I don't 
know if I'm not duplicating some other report or patch.
