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>".

7ddbc95b51 clean up `set!' implementation in ASL to avoid catching failures 
The code seems to pre-date the failure thunk to `syntax-local-value'.
A problem with letting an exception get raised is that it triggers
the `error-value->string' handler, which loads Slideshow pict support
in DrRacket, which loads `racket/draw' at phase 1 --- which isn't
inherenty bad, but a lot of work that can be avoided.

0acf9834f7 make ISL local' and letrec' expand more the old way 
That is, force expansion to use a single `letrec',
 instead of a mixture of `let' and `letrec' that an
 internal-definition expansion would now use.
