This patch fixes a minor bug in texi2dvi. The $txincludes variable is
either empty or begins with a path separator (":"). If $txincludes begins
with a separator, then TEXINPUTS is set to a string containing two path
separators in a row, which TeX apparently interprets to mean something like
"search the default TeX directories". (My copy of TeX may be old -- Version
3.14159 (C version 6.1) -- but it seems like texi2dvi shouldn't put two
separators in a row even if newer versions of TeX do something different.)
The effect of this bug is that I cannot set TEXINPUTS to override a file
(e.g., texinfo.tex) that exists in the default TeX directories.
Please consider adding this fix into the next texinfo release. Thanks!
