texi2dvi changes

[Gavin Smith]

Hello Vincent and everyone else,

Information about the changes to texi2dvi that I've made:

No longer use a trick of renaming the recorder file to *.flz. In fact,
no special tricks at all in texi2dvi to handle this case. So the
recorder file will have the fls suffix, which Vincent pointed out was
what would be expected.

The current working directory is back at the beginning of TEXINPUTS.

If someone uses an "fl" index with the recorder, I expect either the
index to be blank, or to be the recorder file interpreted as TeX
source (a great ugly mess). I've had both happen for different test
files, although am not sure what made the difference. It might work
anyway, by the same fluke that got it to work with MikTeX before.

With a change I prepared to texinfo.tex, fl indices also worked with
the recorder as well as the log file. This change changed the file
extensions that are used for such an index.

I pointed out that the log files were being grep'd a lot to get the
list of generated files. This won't happen as much now.

This was a big change to a complex script with many ways of running
it, so it's quite possible that something's broken. (I've deliberately
refrained from uploading texi2dvi to the FTP site for the last few
revisions for that reason.)

Can anybody try the script with LaTeX source with BibTeX, or else send
me a test case? I want to make sure the BibTeX files are checked
properly.
