18ad15c659 redex: fix `metafunction->pict' width correction for linebreaks 
The revised implementation is more clearly and directly expressed
in terms of table cells that span columns.

Also, avoid `panorama' by removing a useless `inset' that seems
likely to be the reason for the `panorama'.

Unix bitmaps to go with the new tests are missing; Robby plans to
add them.

42847ea523 follow up to William J. Bowman's commit 
- put the tests together with the other define-union-language tests
- fix the docs
- add a release note
- construct the merged language a bit more directly
- properly deal with this kind of thing:
  (define-language L1 (e f ::= 1 2 3))
  (define-language L2 (e g ::= 4 5 6))
  (define-union-language L L1 L2)

cf9b0f774b Change define-relation to compile to a judgment-form, instead of a metafunction. 
Also:
- remove the restriction on the use of unquote in define-judgment-form
- allows limited use (I modes only) of judgment-forms in terms
- allows the use of define-relation with the search/unification
  based random term generation

672910f27b Lots of bad TAB eliminations. 
I started from tabs that are not on the beginning of lines, and in
several places I did further cleanings.

If you're worried about knowing who wrote some code, for example, if you
get to this commit in "git blame", then note that you can use the "-w"
flag in many git commands to ignore whitespaces.  For example, to see
per-line authors, use "git blame -w <file>".  Another example: to see
the (*much* smaller) non-whitespace changes in this (or any other)
commit, use "git log -p -w -1 <sha1>".
