better messages for reference files

[Basile STARYNKEVITCH]

I have another wish for next lout release (I'm using Lout-3.09 in
French, hyphenation is ok to me!): better messages for
bilibographical reference database *.ld files. I noticed that in these
files

1) missing EOL at EOF

2) some comment lines starting with #

3) missing fields in a bibliographical entry (in particular @Tag or
@Type)

4) starting an entry with '@Reference {' instead of '{  @Reference' lines

give error messages which are not enough informative to the
non-expert user. (I even got an internal error sometimes, but [sorry
Jeff] didn't save the input files producing it, since I was in a
hurry).

I also wish that Lout did take into account an LOUTLIB environment
variable overridding the wired in builtin default of
/usr/local/lib/lout/ directory. (I posted such a patch earlier).

Otherwise, I started using the @Diag package for @Tree-s and found it
great. But I have a few minor problems in an incomplete draft of an
internal report (I want references & indexes) :

The sole figure I have appears after the bibliographical references

The index (currently tiny - about a dozen entries) has the word Index
followed by a big white space (2 thirds of the column) followed by the
entries pushed to the page bottom.
